The source for the bio-polymers and natural extracts is selected by considering the total amino acid concentration and the concentration of nitrogen N (%). A single source or a mixture of sources can be used to obtain the desired bio-polymers and natural extracts. The effect of a bio-polymer on a plant differs depending on the source of the bio-polymer. For example, collagen, keratin, and chitosan peptides could be extracted from fish and seafood waste, skin, hides and feathers. Ears, feet, lungs, and stomach tripe contain larger amounts of proline, hydroxy proline, and glycine, but lower levels of tryptophan and tyrosine. Chicken feathers are a good source of keratin peptides. Table.4. Amino Acid (AA) Concentrations from Various Sources. The natural extract containing bio-polymers is prepared by 1) mixing the bio-waste solid by-product with NADES; 2) Increasing the temperature to about 40 ° C to about 80 ° C and mixing constantly at about 600 rpm/min to about 1200 rpm/min. Optionally, the resulting mixture can be filtered and precipitated with an organic solvent (preferably ethanol) then drying the precipitate by freeze drying or oven drying. The biomass prepared by the extraction process according to the present invention has an extraction yield between 45-98%, preferably between 92-98% and a purity level between 80-100%, preferably between 95 -100%. The extraction efficiency, purity of the extracted biomass, and molecular weight of the extracted biomass can be modulated by changing parameters such as the DES or NADES components molar ratio, DES/NADES purity, the reaction temperature, and the solvent to solid ratio. The NADES of the present invention can be recycled and reused or can be included in the agricultural formulation without purification. The extracts obtained using this method are food grade and can be used in various applications without risk of toxicity. The extraction process can be combined with other steps such as dry or wet chemical engineering by adding a functionality group, ball-milling, ultrasonication or microwaving to produce individual single-chain bio-polymer composites or chain folding nanoparticle composites. The process allows one to control the precursor chain (e.g. different bio-polymer molecular weights), add other molecules to the bio-polymers (e.g. bioactive agents), dictate the properties of the final nanoparticle (e.g. targeting, anchoring, etc.), and control the nanoparticle size and shape, thus, allowing for the production of distinct, custom molecules. Different sizes and shapes of nanoparticles encapsulated with dicamba are shown in Figure 3, and atrazine is shown in Figure 8. Extraction of the biomass with NADES combined with ball milling or ultrasonication produces small molecular weight peptides, microwires, nanowires and nanospheres. Ball milling is a mechanical process using a planetary ball milling at speeds between 50 to 800 rpm, used during the extraction with NADES. Ball milling combined with NADES extraction can result in higher yields, shorter extraction times and higher purity than a simple NADES extraction. Bio-polymer structural and physico-chemical properties can be modulated, for bio-polymers of various molecular weights, structures and compositions can be obtained. Using various rpm and different solvent with or without specific temperatures allows one to modulate the shape of the extracted bio-polymers, such as synthesis of nano and micro wires, and nano spheres, and possibly other shapes. Different shapes can be obtained by changing the surface energy of the molecule. Further, the addition of a secondary active ingredient, and its functionalization on the surface of the resulting nano bio-polymer or its encapsulation into the nanoparticles, or both can be achieved. When ultrasonication is used, the bio-polymers are hydrated in DES or NADES between 10 min and 3 hours, preferably for 30 minutes - 1 hour, at temperatures between 40-120 ° C, followed by sonication between 150W to 800 W for 3 minutes to about 45 minutes, but most preferably between 3 min to 20 min to produce the nano bio-polymers. When using DES or NADES for the extraction of the bio-polymers, sonication can be performed in the same liquid, during or after the bio-polymer extraction. Sonication allows the formation of nanoparticles and microparticles and it assists in both the particle surface functionalization and encapsulation, and reorientation of the nanoparticles. For instance, a bioactive compound can be encapsulated by adding the bioactive agent and sonicating again. The bioactive compound can also be released by exposing the encapsulated nanoparticles to sonication. Figure 6, lower right panel, shows the release of the Dicamba-Gentian Violet, intense blue violet color when exposed to an ultrasonic bath for 5 minutes as compared to the non-sonicated keratin nanoparticle which has a lighter violet color. The natural extracts containing bio-polymers can be used directly in agricultural formulations as a biostimulant or engineered bio-polymers can be prepared by attaching one or more functional molecules to the extracted bio-polymers. The functional molecules include but are not limited to additional peptides, polymers (chitosan, gellan gum, cellulose, natural gum, rosin, paraffin, xanthan, alginate, agarose, polysaccharides, dextran, carrageenans, starch, albumin, polyacrylamide, polyester, polymethacrylate, polyamide, polyurethes, polycyanoacrylates, etc.), co-polymers, metal complexes, plant bioactive molecules, microelements (e.g. zinc, iron, manganese, copper, molybdenum, boron, chlorine or nickel), crosslinkers, or a combination thereof. The functional molecules are attached to the bio-polymer either covalently or non-covalently using linkers. The resulting engineered bio-polymer can have a chain shape (targeted bio- polymer), or they can self-assemble into nanoparticles (nano bio-polymer). Nano bio- polymers have an interior, exterior and an average diameter (hydrodynamic radius) between 1-1000 nm. Functional molecules can be embedded non-covalently with the bio- polymer and the resulting nano bio-polymer usually has a spherical shape. A functional linker can be added to an extracted bio-polymer dissolved in water or NADES. Bioactive agents can be added to an aqueous/or non-aqueous bio-polymer solution and the bioactive agent can be cross-linked or encapsulated on or in the bio-polymer or nanobio- polymer, and the bio-polymer and nano bio-polymer can act as a delivery system. See Figure 5 which shows the TEM images of extracted keratin product delivery systems of various sizes and shapes synthesized via metal precursors (Figs. 5A-L); via amine addition (Fig.5M); via calcium stearate (Fig.5N) or nano-micro delivery systems resulting from an extraction using Urea-Na2S (Fig, 5L). UV-VIS absorption of various delivery systems is shown in Figure 5O. Keratin-metal complexes of butterfly shape, dimer, trimers, wires or simple nanospheres can be synthesized using the present invention. In one embodiment using a metal precursor, langbernite and rock phosphate were used to obtain organic nanodelivery system composites. A change of color was observed in both cases, black grey solution for rock phosphate nanoparticles, and yellow for langbernite. The rock phosphate delivery systems can be obtaining by functionalizing them with an additional component. When the delivery system is used, the rock phosphate nanoparticles are exposed at a ratio of nanoparticles: additional component in a weight ratio of 1:10 and mixed for 1 h at room temperature and pH=7.4, then centrifuged at 5000 rpm for 20 min. Figure 5P, shows the UV-Vis absorption spectra confirming both the formation of nanoparticles, having an absorption around 270 nm, (red line) and the formation of the delivery system with two absorption wavelengths, one corresponding to the nanoparticles at 274 nm, and one to gentian violet at 590 nm The bio-polymers and nano bio-polymers can also have a gel or nanogel structure or they can be polymerized to enriched biopolymers by adding an additional component to form a waxy complex. The bio-polymers can be engineered using a dry or wet chemical reaction, pH modulation, precipitation or a combination thereof. The reaction can be initiated by addition of water 5-25% by weight ratio of the extract. A fatty compound can be added to produce a clay, wax enriched biopolymer, (around 1-15% fatty compound modification of biopolymer). Additional agricultural components can be added to develop specialized agricultural products. For example, an enriched biopolymer formulation can be synthesized for use as a seed priming or seed coating composition (see Example 11). Nanoparticles, and nanodelivery systems can be formed by precipitation with a solvent, Tris buffers of various concentrations, such as 1 mM, 3 mM, 5 mM, 10 mM, and 20 mM; preferably 10 mM; or acetone, methanol, ethanol, or water, at various pHs can be used depending on the desired size of the nanoparticles. Proteins close to the isoelectric point will result in smaller nanoparticles. The increase elecronegativity of a pH around 7.3 to 9 results in bigger nanoparticles. Increasing the elecronegativity to a corresponding pH of 10 or above, causes the nanoparticles to collapse. Different shapes can be obtained by modulating the pH and the electronegativity at which the precipitation is carried out (see Figures 3 and 5 and Example 12). Other classes of bio-polymers or extracts can be extracted and manipulated using the present invention. The polysaccharide chitin was extracted from shrimp shells, engineered to different sizes, and encapsulated with active agricultural compounds for various applications (see Figures 6 A-H which show TEM images of acetylated chitin encapsulated with different pesticides. The UV-vis absorption spectra confirms the encapsulation (See Figure 6I-J). There are two types of delivery systems commonly used with agricultural formulations (1) systemic delivery systems which transport the encapsulated active compound into the plant and release it inside the plant; and (2) contact delivery systems which break when they contact the plant leaves and release the active compound. Systemic delivery systems can take longer to act, but they can be more effective because they work throughout the plant. Contact delivery systems can produce an immediate effect, but the effect does not last long. Each delivery system has pros and cons, and a customized delivery system formulation designed for specific applications could be used to control the delivery of the bio-polymer formulations and lower the indirect impact of the formulation on biota, humans, plants, soil and the environment. In the present invention, the delivery system can be customized by controlling the surface chemistry. Additional functionalities can be incorporated into the delivery systems, for example, anchoring or targeting molecules can be attached to the surface of the delivery system. The delivery system can be a chain bio-polymer or a nano bio-polymer. In a preferred embodiment, a peptide anchoring molecule which acts as an adhesion promoter to hydrophobic surfaces and the waxy plant surface can be attached to the surface of the bio-polymer chains or nano bio-polymers for a contact delivery system. Enhanced adherence to the plant results in improved internalization, as well as controlled release of the chemical and intracellular targeted delivery. The resulting agricultural formulation can be applied to crops in any type of atmospheric conditions. The adhesion promotor results in adherence to the leaf surface, where the contact delivery system controls the release of the encapsulated active compound. This combines the benefit of an immediate effect with time-controlled release and reduces reapplication. Moreover, since the bio-polymers or nano bio-polymers can adhere to the leaves, the formulation offers protection against leaching off due to rains, avoids volatilization, reduces possible biota negative effects, and reduces plant and target overexposure. When extended or sustained release is desired after application, the trigger for release can include but is not limited to a pH change, a temperature change, a barometric pressure change, an osmotic pressure change, exposure to water, exposure to a solvent, changes in shear forces, exposure to a bacterium or exposure to an enzyme. In addition, a nanoparticle can be used which has a pore network and releases the encapsulated bio-polymers by diffusion. Using a delivery system, the nutrient input (nitrogen or phosphorous) in crop production can be precisely controlled which will reduce the impact of the fertilizer on the health of the soil, ecosystem and people. In many state of the art compositions losses of up to 80% of the total agro-chemical quantity occur per application. Delivery systems can decrease the high losses of chemicals, reduce the over-application and the run-off of the active toxic chemicals. Based on their nanoscale properties, formulations containing nano bio-polymers will be more potent, will require lower application doses, can be used in lower concentrations, and will improve productivity as compared to conventional formulations. Plant physiology- growth stimulation can be controlled directly by internalization of nano bio-polymers into various cellular compartments, or plant physiology- growth stimulation can be influenced by targeting the soil microbiota to enhance their communication with the plant for plant growth, development, and protection. In addition to peptide anchoring molecules which act as adhesion promotors, bioactive molecules, pH sensitive molecules, thermo-responsive molecules, or a combination thereof can be linked to the bio-polymers or nano bio-polymers resulting in bio-polymers and nano bio-polymers having specific responsive properties which can be used as smart targeted delivery systems. The bioactive molecules can be linked directly to the initial bio-polymer, and the initial bio-polymer can be used as a targeted delivery system. In another embodiment, the targeted delivery system can include functional polymers which have bioactive molecules linked to a polymer or co-polymer. The functional polymers are attached to the initial bio- polymer to form the engineered bio-polymer and nanobio-polymer. The functional polymers can be a single molecule sequence which is attached to the surface of the bio- polymer or nanobio-polymer. The functional molecules and the initial bio-polymerscan both act as bioactive molecules. Bioactive molecules can also be encapsulated within the nanobio-polymers, bio-polymer gels or nano bio-polymer gels, and their surface can be further functionalized by attaching additional targeting molecules, anchor molecules, or combinations thereof. The bio-polymers and nano bio-polymerscan be formulated to be pH responsive by selecting different sources of peptides with strategic isoelectric points. In addition, pH sensitive molecules can be attached to the bio-polymers and nanobio-polymers. The pH sensitive molecule can be a peptide, or a polymer, co-polymer or a combination thereof that responds to changes in the pH of the environment. When the pH of the surrounding medium changes to the designated pH, the delivery system will release the bioactive compounds immediately or at a controlled rate over a period of time. In addition to changes in pH, the trigger for release can be a temperature change (thermo-responsive), barometric pressure change, osmotic pressure change, exposure to water, exposure to a solvent, changes in shear forces, application of the formulation, exposure to a bacteria, exposure to an enzyme, exposure to electromagnetic radiation and exposure to free radicals, depending on the functional molecules which are attached to the bio-polymer and nanobio-polymer. The release of the bioactive molecules can also be controlled by using nano bio-polymers with a specific structure such as a cavity or a network structure to encapsulate the bioactive molecule. The bio-polymer and nano bio=polymer can be combined with other beneficial agents including but not limited to plant growth regulators, bactericides, fungicides, insecticides, acaricides, miticides, nemanticides, molluscicides, herbicides, plant nutrients (e.g. potassium, phosphate, carbohydrates, and amino acids), preservatives, microelements, humectants, detergents, fertilizers, chelating compounds, organic acids, surfactants, dispersing agents or combinations thereof. Formulations containing bio-polymers and/or nano bio-polymers can be used as herbicides. The protein:herbicide can be prepared at a weight ratio 1:3; 1: 6: 1:6.6; 1:10:1:16.6; 1:30 or 1:60. The formulation can be made to correspond to 2.25 kg Dicamba application per Ha, or can correspond to a lower or higher concentration. Additionally, the nanoparticle-herbicide delivery system can be preserved for up to 1 year. A DES ChCl: Glycerol, can be prepared at a different molar ratio, such as 1:1; 1:2; 1:3; 1:4, preferably 1:2, and preferably between 1-3 % of glycerol in the final diluted application formulation. No preservatives or softeners or anti-volatile compounds are necessary. The herbicide delivery systems can be added to various agricultural formulations, or can be combined with other herbicides that are known in the art. Formulations containing bio-polymers and/or nano bio-polymers can be used as fertilizers. A multipurpose fertilizer can be prepared using 5-30% extracted bio-polymers, nano bio-polymers or a combination thereof. The bio-polymers can be extracted from any bio-source and the nano bio-polymers can be formed by a crosslinking reaction or precipitation. The fertilizer base formulation contains 5-30% extracted bio-polymers and/or nano bio-polymers, 10-30% nitrogen, 2-20% phosphorus, 2-20% potassium, 2-8% chelated microelements or nanoelements, 10-30% amino acids and 1-3 % carbohydrates. The initial bio-polymerscan contain one or more chelated metals. A fertilizer composition for metal deficient crops can include 3-30% bio-polymers chelate formed with 0.1-3% metal ions selected from iron, zinc, manganese, and copper and/or 3-30% nano bio- polymers with 0.1-3% metal ion nanoparticles (e.g. iron nanoparticles, zinc nanoparticle, manganese nanoparticles, and copper nanoparticles) encapsulated therein. Anchoring molecules such as anti-microbial peptides are preferably attached to the extracted bio- polymers or nano bio-polymers. Extracted bio-polymers and nano bio-polymers have a high impact on plant physiology. In addition to acting as a biostimulant, extracted bio-polymers and nano bio- polymers can also alleviate the negative effects of abiotic plant stress due to salinity, drought and heavy metals. Extracted bio-polymers and nano bio-polymers directly affect plants by stimulating carbon and nitrogen metabolism and interfering with hormonal activity. Indirectly, bio-polymers and nano bio-polymers could enhance nutrient availability in plant growth substrates and increase nutrient uptake and nutrient-use efficiency in plants. Bio-polymer and nano bio-polymer delivery systems that carry a bioactive agent act as both a bio-stimulant based on their polymer composition, and as a stimulant based on the function of the bioactive agent. For example, when the bioactive agent is selected from a class that targets a pathogen the bio-polymer delivery system acts both as a biostimulant to stimulate plant growth and the immune system, and as an anti-pathogen to treat and/or protect the plant from various diseases. The bio-polymers and nano bio-polymers are designed to have a specific size, surface charge and conformation. Functional groups can be attached to the initial bio-polymer structure to provide specific characteristics such as mechanical stability, pH or temperature responsive properties, or specific denaturation properties. Extraction of Initial Bio-polymers A diversity of products can be extracted using the process of the present invention. The DES/NADES of the present invention can also be used to dissolve a product or used in a formulation to preserve a product or a combination of products. The extracted or dissolved material can include but are not limited to a protein, a DNA, a RNA, a polysaccharide, an enzyme, a toxin, a flavonoid, an anthocyanin, a colorant, an alkaloid, a terpenoid, a phenylpropanoid a glycoside, a phenolic compound, a colorant, a flavor, a fragrance, a dye, an herbicide, an insecticide, a pesticide, a biostimulant to the plant, a biocide or a mixture thereof. The resulting products can be used in many applications including but not limited to agriculture, food, and cosmetics. The initial bio-polymerscan be extracted from any organic materials, preferably the initial bio-polymers are extracted from bio-waste materials. The bio-waste sources can be animal in origin and can include any animal by products including but not limited to animal epithelial or connective tissues, blood meal, fish tissue, feathers, hair, bones, skin, shellfish shells, wool waste from clothing manufacturing and leather by-products. The bio- waste sources can be plant in origin, including but not limited to crop waste (corn stalks, sugarcane bagasse, prunings and culls), food processing by-products (corn cobs, chaff, straw, pomace), brewery waste (spent grain) and wood. The extraction of the biomass using NADES can be tailored by choosing different types of NADES/DES, with specific acidity, basicity, composition and molar ratios, to control the molecular weight, size, purity, and structure to obtain nanosized, microsized, nanowired and nanoparticles of different shapes and sizes. They can also be combined with methods such as a dry chemistry method, a wet chemistry method or metal oxide methods, for reducing the size of the bio-polymers, and to encapsulate and/or surface functionalize the resulting products. Additionally, the extraction can be combined with methods such as assisted ball milling or ultrasonication. By combining NADES with ball milling and ultrasonication, novel bioactive components can be easily functionalized to the bio-polymer surface or encapsulated inside or between their structure or all of the above, and the resulting compound has novel properties. Further, ball milling and sonication reduce the extraction time, increase the efficiency of extraction, and lowers the costs. After extraction of the biomass, the NADES can be recycled or can be left in the agricultural formulation. NADES does not have adverse effects on humans, plants, or the environment and in some cases, the NADES can act as a bio stimulant to the plant. NADES can achieve a biomass extraction yield between 85-98%, preferably 92-98%, and purity between 80-100%, preferably 95.3 to 100%. The initial bio-polymer can be engineered to carry one or more bioactive compounds, and release them in soil/hydroponic media or on plant leaves, or to deliver them inside the plant, all in a controlled, targeted and timely manner. The engineered bio-polymer, can be used as a smart delivery system in agricultural formulations. The smart delivery system can minimize leaching while improving the uptake of nutrients by plants and can mitigate eutrophication by reducing the transfer of the bioactive compound to the ground. More than 85% of conventional fertilizers and pesticides are leaching into rivers, degrading and volatilizing. Leaching, volatilizing and degrading can be avoided or reduced by encapsulating agricultural formulations into nanoparticles or gels. The chemicals are internalized into the plant inside the nanoparticle and/or on the surface of a nano bio-polymer or bio-polymer. Moreover, the nano bio-polymer allows improved delivery, targeted accumulations and controlled releases of the attached or encapsulated agricultural agent into the plant. The structure and function of the encapsulated/attached bioactive compounds are protected by the bio-polymer, which provides increased solubility and resistance against hydrolysis and photodecomposition. For example, it has been reported that 75-95% of phosphorous fertilizers form complexes and/or precipitates in the soil, and only 5-25% is absorbed by the plant. The delivery systems of the invention efficiently deliver a phosphate precursor nutrient resulting in greater phosphate efficiency and lower losses. Moreover, herbicides and pesticides are well known for their toxic effects both on the environment and humans. Encapsulating pesticides and herbicides will result in a lower volatilization loss, thus protecting the environment and human health. In addition, lower dosages of encapsulated chemicals are needed to provide the desired effect. Since the bio-polymers are bioactive compounds (i.e. act as nutrients), when applied in combination with pesticides and/or herbicides, the formulation provides both protection and stimulates plant growth. The formulations can be applied as a component of a seed coating blend. Seed treatment formulations with extracted bio-polymers and nano bio-polymers mixed with antimicrobials, fungicides and insecticides can reduce later pesticide applications. Bio-waste means a raw material which consists primarily of the organic residue from processed materials. Bio-waste can include but is not limited to (1) animal by- products left after processing of meat and seafood (bones, tendons, skin, the contents of the gastro-intestinal tract, blood and internal organs, feet, feathers, shells, hair, etc.) , waste from the garment industry (hide, wool, etc.); (2) plant by-products including but not limited to crop residue, plant parts leftover from the production of food, weeds, leaf litter, sawdust, forest waste, paper mill sludge, and livestock waste (manure); (3) yeast by- products including but not limited to waste yeast produced by fermentation, and (4) municipal waste. Extracted bio-polymers encompass at least one peptide, lipid or polysaccharide that was extracted from bio-waste; a combination of peptides, lipids and/or polysaccharides extracted from bio-waste, cross-linked peptides, lipids and/or polysaccharides and engineered extracted peptides, lipids and/or polysaccharides, or a combination thereof. The term peptide refers to a compound comprised of amino acid residues. A peptide must contain at least two amino acids, but no limitation is placed on the maximum number of amino acids that can comprise a peptide sequence. As used herein, the term refers to both short chains commonly referred to in the art as peptides, oligopeptides and oligomers, and to longer chains, which generally are referred to in the art as proteins. An engineered bio-polymer has at least one functional group attached to its surface. A functional group, is any molecule which changes the properties of the bio- polymer such as a bioactive molecule, an additional polymer, a co-polymer, a linker, a targeting molecule, an anchoring molecule, a pH responsive molecule, a thermosensitive molecule and combinations thereof. A gel is a semi-solid nonfluid polymer which has a dilute cross-linked network within a fluid. A nanogel is a nanoparticle composed of a hydrogel containing a highly cross- linked polymer network. Nano gels are 3-1000 nm in size. A pH sensitive or pH responsive molecule responds to changes in the pH of the surrounding environment by changing properties such as size or shape.

Targeted bio-polymers refers to specific classes of bio-polymers that are structurally targeted towards a specific application. They are tailored to meet specific requirements for degradation, bioactive molecule release or incorporation of different hydrophobic or hydrophilic tails. Targeted bio-polymers can be used to control surface charge, pH and stimuli responses, denaturation and targeted delivery to a specific site. Anchoring or internalization peptides can be attached to the bio-polymers surface. Anchoring peptides such as antimitotic peptides enhance their adherence to plant leaves. Cell penetrating peptides (CPPs) can enhance the transport of the bio-polymers into cells and specific cell compartments. Anchoring peptides refer to a specific class of peptides which in addition to their defense-related properties (e.g. antibacterial, antifungal, antiviral, anti-oxidative activity, and chitinase and proteinase inhibitory activities), display “peptide promiscuity”, which refers to multiple functions displayed by a single peptide. The anchoring peptides have the ability to increase the attachment to the surface of the waxy plant leaves, which allows the agricultural formulation to be applied in any conditions, including rain, by reducing run off of the formulation. These classes of peptides have a sequence less than 100 amino acids, preferably between 10-100 amino acids, and contain specific variations of amino acid constituents. These peptides have a MW of 2–125 kDa, preferably 2-6 kDa. In addition, their amino acid structure is compact with high thermal, chemical, and enzymatic anchoring properties. The anchoring peptides have specific secondary and/or tertiary structures and contain two or three domains: N-and C-terminal pro-domains or N-and C- terminal pro-domains and a third domain which can be a mature function related peptide domain. The third domain has an antimicrobial, antifungal, antiviral, and/or anti-oxidative activity, chitinase and/or proteinase inhibitory activities, anchoring activity or a combination thereafter. Anchoring peptides have the ability, when applied on plants, to organize into specific structures with conserved structural folds that enable sequence variation of amino acid residues that are encased in the same scaffold within a particular structure. The anchoring peptides include but are not limited to peptides from families including thionins, defensins, hevein-like peptides, knottin-type peptides (linear and cyclic), lipid transfer proteins, α-hairpinin families, snakins, Glycine-rich peptide, His-rich peptide shepherins, eGFP-anchor-peptide fusion protein, Plantaricin A (22 aa), Cn-AMP1 and Cr-ACP1.

Nano bio-polymers produce high internalizations in plants. Additionally, they can be formulated to be responsive to pH and/or temperature or their surface can be modified with anchoring or targeting molecules. Nano bio-polymers with specific properties can be made by selecting specific classes of bio-polymers and modifying their physical-chemical properties, their log P and/or by incorporating anchoring molecules, targeting agents and/or internalization molecules. The nano bio-polymer composition may be formulated for foliar application to penetrate the stomatal pores of the plant leaves and/or the nano bio-polymer composition can be applied on the soil and taken up through the soil by the root systems in plants.

Different carbohydrates, dietary fiber, sugars fat, protein, vitamins, and acids can be extracted using the same method but changing the reaction conditions, NADES type, time, and/or temperature. For instance, in order to extract collagen with an efficiency of 92.5% to 98%, and a purity of 95.3% the reaction time is between 2-4 hours at a temperature between 65- 80°C. The pH is adjusted to 4.5 - 7.0. The solvent: solid ratio is between 80:1 to 200:1, preferably 170:1, and can be modulated to result in low or high molecular weight peptides. The initial peptide and the chain peptides (PHs) can have a molecular weight from about 2kDa to about 1000 kDa, preferably from 2kDa to 500 kDa, more preferably 2kDa to 50 kDa. The optimum extraction for high molecular weight peptides is ChCl-OA (1:1.0)/waste (80:1, mL/g) at 65 °C for 2 hours; for low molecular weight peptides the optimum extraction is ChCl-OA (1:1.0)/waste (120:1, mL/g) at 65 °C for 6 h.

Wet-Chemistry Crosslinking using Covalent and Non-covalent Functionalization The initial extracted bio-polymer is engineered using a functionalization reaction, such as attaching at least one functional group or a combination of functional groups, at a specific pH, to the initial bio-polymer at targeted groups as shown in Table 3. Specific structures such as a chain like structure; a self-assembled nanoparticle structure; or their gels can be produced. Additional functionalization can be performed to attach distinct functional groups, or a combination of functional groups, either to amino acids of the initial peptide or to previously attached functional groups, or both. In other words, a first functionalization is performed by adding the first selected functional groups or the combination of functional groups to the initial bio-polymer surface. Subsequently a second functionalization is performed by attaching the second selected functional groups, or a combination of functional groups to the engineered bio-polymer resulting from the first functionalization. A third functionalization is performed by attaching the third selected functional groups to the engineered bio-polymer of the second functionalization. Additional functionalization can be carried out. Linkers can act as intermediates between the desired functional molecules and the targeted groups which form the extracted bio-polymer structure. The targeted groups of the possible extracted compounds listed above are the amines (NH 2) , carbonyl group (COOH), hydroxyl (OH), sulfhydryl (SH), aldehyde (CHO), or azide (N3) groups or a combination thereof. For instance, when isolating a peptide, amino acid groups from the peptide structure can be targeted. The intermediate linker is selected from a class of linkers that have at least two reactive ends, wherein one end has affinity to the targeted amino acids of the peptide, and binds to the peptide covalently, and the second reactive end can bind to specific functional groups to produce the engineered peptides. Various conformations of functionalized bio-polymers can be obtained, such as bio-polymer chains, nanoparticles/microparticles, nano bio-polymers or their gels. Suitable linkers include but are not limited to the linkers shown in Table 3. Table 3. Preferred Covalent Functionalization of the Extracts using Linker Intermediates
Keratin is recognized for its reactive cysteine amino acids. Covalent bonding of cysteine with amine-modified functional molecules can be performed in the presence of a linker, wherein the linker can be selected from: maleimide, haloacetyl (bromo or iodo-), pyridyldisulfite, thiosulfate, and vinylsulfone linkers. The resulting bioactive compound- keratin chains, nanoparticles or gels, can be used as a bioactive delivery system to enhance plant growth and development, to provide support during harsh environmental conditions, to treat various pathogens, or a combination thereof. The engineered peptide can be synthesized using non-covalent bonds to the initial peptide structure, wherein a negatively charged functional group preferentially interacts with a cationic group, and a positively charged functional group preferentially interacts with an anionic group. The surface charge, size and conformation of the complex can be modulated by varying the concentration of the functional group. An initial peptide, with a specific pKa and surface charge, is added to a solvent or aqueous solution at a pH between 4.5-8, wherein the pH is selected to be above the pKa of the initial peptide. A different surface charge functional group is added to the peptide solution, and the mixture is reacted at room temperature between 10-30 min. The mass ratio peptide:functional group is chosen and modulated based on the desired final peptide or nanopeptide, z- potential, size, and stability. The ratio of functional groups to the initial peptide can be between 1:1 to 1:50,000 (w/w). The functional groups can be both hydrophilic and hydrophobic and include but are not limited to linkers, another peptide, polymers or copolymers (natural or synthetic), a nanoparticle, a bioactive molecule, or a combination thereof. Bio-polymers or nano bio-polymers having increased stability, can be produced by attaching a PEG tail to the peptide. Bio-polymers or nano bio-polymers having anti- fouling and anchoring properties to the plant leaves, can be produced by attaching an anti-microbial peptide functional group or a polymer, resin or another component that acts as anchoring agent to form superior adhesiveness to the plant leaves Bio-polymer or nano bio-polymer delivery system compositions that carry a bioactive molecule can be customized to accommodate various amounts, or combinations of bioactive ingredients, by modulating the initial peptide type, size, molecular weight, and the ratio of peptide: bioactive molecule: functional group. The functional groups of the invention can be engineered before the attachment to the initial peptide, and one or more distinct functional groups can be attached through a covalent or non-covalent bond. The engineered bio-polymers can also carry biological molecules attached to its surface. In the case of nano bio-polymers, the biological molecules or the polymer/copolymer, or both can be attached on the surface of the nano bio-polymer, can be encapsulated inside the nano bio-polymer, or both. The biological molecule can be entrapped in the bio-polymer or nano-biopolymer by inserting them into a solution containing the biological molecule(s), wherein its absorption is controlled by pH, followed by the swelling of the engineered nano bio-polymer or gels. The biological molecules can be attached using linkers (covalent bonding) or by non-covalent bonding. Polymers or other biological molecules can be attached to the initial extracted bio-polymer, either before the non-covalent interaction with the functional group, or after the non-covalent interaction. The initial bio-polymers and engineered bio-polymers can be used as a platform delivery system for the delivery of at least one bioactive agent. Bio-polymers extracted from various sources can be produced in various sizes, with different surface charges, different conformations, and in different compositions tailored for specific applications related to the function of the bioactive agent. The loading capacity (LC) and encapsulation efficiency (EE) is calculated based on the formulas below. Using the EE varies between 30-62% depending on the method chosen, initial peptide and the final composition. A non-covalent crosslinking reaction can be performed by attaching a functional group from a class of metal complexes to the surface of the bio-polymer. For example, a phosphate precursor (calcium phosphate, sodium tripolyphosphate (TPP), etc.) can be attached using non-covalent interaction. Using TPP, the extracts from seafood chitosan can be synthesized to encapsulate various bioactive agents to treat a plant or to enhance its growth. The mass ratio chitosan: TPP can be 10:0.5, preferably 5:1, and the chitosan to encapsulated bioactive agent ratio can be 5:0.3-1. The resulting average nanoparticle size is between 20-400 nm, increasing with the bioactive agent concentration.

Agricultural Formulations The bio-polymers and nano-biopolymersof the invention are used as novel effective smart materials or ingredients for sustainable intensification in agriculture to improve crop production and to manage plant disease. Bio-polymers, engineered bio- polymers, and micro or nano bio-polymers can be used to stimulate plant growth and development, stimulate root growth, increase adsorption of nutrients, increase crop yield, improve quality and taste of crops, increase amino acid or other nutrient content, and for protection against various pathogens. Bio-polymers and nano-biopolymers can be included in agricultural formulations and nanoformulations, such as fertilizers, pesticides, and herbicides. The compositions containing bio-polymers and/or nano-biopolymers can be used in certified organic farming that uses zero synthetic chemicals since the extracts are organic and have no adverse effect on the environment or humans. The invention provides a process for making and customizing an agricultural active ingredient and an agricultural formulation. The agricultural formulation can be made in a one pot process as described in the following steps. Step 1. Initial Bio-polymer Extraction Solid waste is combined with a natural eutectic solvent (DES/NADES) to extract the bioactive polymer. The bio-polymer can be a peptide, polysaccharide or lipid. Step 2. Separating the Bio-polymer The extracted bio-polymer can be used in an agricultural formulation without further processing or the extracted bio-polymer can be separated from the reaction liquid by precipitation with organic solvents, followed by filtration, to isolate a pure bio-polymer. The extracted/isolated bio-polymer can be combined with various other bioactive components and used as an organic or conventional fertilizer. Step 3. Engineering the Bio-polymer. Optionally, the bio-polymer extracts of Step 1 can be further engineered, either in the same liquid solution; or the solution can be separated and the bio-polymer can be re-dispersed in an aqueous solution, or other solution (different NADES, or buffered aqueous solution). The bio-polymer extracts can be combined in a dry form with a functionality group to produce an engineered enhanced bio-polymer, a nanowire, a nanoparticle, or a delivery system. The engineered bio- polymer delivery system can be utilized as an intelligent fertilizer, herbicide, pesticide, or insecticide, or a combination thereof. Step 3A. Produce Nano bio-polymers using sonication. After sonication, the nano bio- polymers can be used in an agricultural formulation or nanodelivery systems can be produced by adding a bioactive agent, followed by additional sonication to encapsulate the bioactive agent inside the nano bio-polymers. The nano bio-polymer delivery system can be utilized as an intelligent fertilizer, herbicide, pesticide, or insecticide, or a combination thereof. Step 3A’. Multi-Responsive/Intelligent nano bio-polymer Delivery System. The nano bio-polymers produced by sonication can be used in an agricultural formulation or they can be further engineered by attaching specific anchoring, targeting, pH responsive and/or thermosensitive molecules to its surface. The resulting multi- responsive nano bio-polymers can be used in a multi responsive intelligent fertilizer, herbicide, pesticide, and/or insecticide. Step 3B. Bio-polymers with Ball Milling. The extracted bio-polymer of Step 2 can be subjected to ball milling to produce nano bio- polymers. The resulting nano bio-polymers can be used in agricultural formulations or used to produce nanodelivery systems. Step 3B’. Nanodelivery Systems or Multi-Responsive/Intelligent nano bio-polymers Delivery System. The nano bio-polymers of Step 3B can be used to encapsulate a bioactive by simply adding the desired bioactive compound to the ball milling solution. The resulting nanodelivery system can be used in agricultural formulations. Step 3B” Multi-Responsive/Intelligent nano bio-polymer Delivery System. The nano bio-polymers produced by ball milling can be used in an agricultural formulation or they can be further engineered by attaching specific anchoring, targeting, pH responsive and/or thermosensitive molecules to its surface. The resulting multi- responsive nano bio-polymers can be used in a multi responsive intelligent fertilizer, herbicide, pesticide, and/or insecticide. The bio-polymers can be used directly in agricultural formulations or combined with other components. In addition to bio-polymers and nano-biopolymers the agricultural formulations can include a) other nanocomposites (e.g. zinc oxide, titanium oxide, copper oxide and/or any metal nanoparticle form of the disclosed microelements), b) other bioactive compounds including but not limited to pesticides, herbicides, bactericides, fungicides, insecticides, acaricides, miticides, nemanticides, molluscicides, growth regulators, and sources of N, P and/or K, c) compounds which provide sources of carbohydrates (sugars, molasses, etc.), d) macronutrients including but not limited to magnesium, calcium, sulfur, and/or their precursors in the form of metal salt or a nanoparticle, e) metals including but not limited to Bo, Fe, Mn, Zn, Co, Cu, Mo, and/or Mg or precursors thereof, and/or f) other beneficial compounds including but not limited to carbon nanoparticles, carbon nanotubes, graphene, aluminum, silicon, or precursors thereof, in their bulk form or in nanoform. The agricultural formulations can be used to enhance plant growth and development and to protect the plant against various pathogens or a combination thereof. Agricultural fertilizer formulations can contain a mixture of bio-polymers and nano- biopolymers and essential plant element precursors. Various concentrations and ratios of bio-polymers and nano-biopolymers can be combined with one or more of the 17 essential elements as listed in Table 5. Preferably, fertilizer agricultural formulations include nitrogen (N), phosphorus (P) and potassium (K). The nutrient input attributed to applying the bio-polymers and nano-biopolymers fertilizer on crops results in an increase in crop yield between 30% to 80%. Table 5: Essential plant nutrient elements and their primary form utilized by plants. Essential plant element Symbol Primary form
Bio-polymers and nano-biopolymers can be added to conventional N,P,K fertilizer formulations at a concentration between 5-25% hydrolyzed peptide, preferably 5%-10%. Carbohydrate compounds can be included at a concentration of about 1%. The carbohydrate compounds are preferably derived from industry by-products, and include but are not limited to molasses, humic acid, polyglucuronic acid, and pectin. The polyglucuronic acid and pectin can be hydrolyzed in basic media for 30 min-2 hours at 40-60 ° C before adding to the formulation. The fertilizer formulation can also include 0.1%- 0.5% microelements such as Bo, Fe, Mn, Zn, Co, Cu, Mo, Mg, and preservatives. Preferably, the sources of nitrogen, phosphorus and potassium are organic such as yeast extracts. The pH of the fertilizer is preferably 2.5-4 to reduce microbial attacks. A N, K, P fertilizer can be formulated to include 1) an initial bio-polymer that is engineered to nano bio-polymers and encapsulated with a N source to form a nanocomposite, 2) an initial bio-polymer that is engineered to nano bio-polymers and encapsulated with a K source to form a nanocomposite, 3) an initial bio-polymer that is engineered to nano bio-polymers and encapsulated with a P source to form a nanocomposite. The nanocomposites can be combined with one or more nanoparticles, including but not limited to zinc oxide, copper oxide, iron oxide, titanium oxide, calcium oxide, nickel, aluminum, silicon, and carbon. The nanoparticles can be in the solution, attached to the nano bio-polymers, or a combination thereof. The concentration and ratio of encapsulated N, K, and P is customized based on the plant’s needs. The N, K, P fertilizer can include 5-75% phosphorus, preferably 55%; 5-55% nitrogen, preferably 25%, and 5-75% potassium, preferably 20%. The nanocomposite sizes can be between 10- 1000 nm, but are preferably between 100-200 nm. Additionally, the nanoparticles can be of different sizes and shapes such as spherical, cubic, rod, rhombic, wires, chains, etc. An N organic fertilizer can be formulated containing 1) 5-25% selected hydrolyzed bio-polymers; 2) 2-10% enzyme extracts, and 3) 1-3% carbohydrates. The bio- polymerscan further contain an anchoring peptide on its surface to increase attachment of the fertilizer to the hydrophobic leaves of the plant. The fertilizer can be applied in a liquid form at an adjusted pH of 2-4. An N, K, P organic fertilizer can be formulated containing 1) cross-linked initial extracted bio-polymer gels, wherein the bio-polymer is in an amount between 5-35%, preferably 5% -10%, 2) one or more bioactive compounds absorbed inside the bio- polymer gel, wherein the bioactive compounds include N, K, and/or P, 3) optionally, yeast extract in an amount between 2-13%; and 4) digested carbohydrates in an amount of 1%. Optionally, the bio-polymer can comprise anchoring peptides for enhanced attachment and internalization to the plant. The fertilizer can be in a liquid, powder, or gel form and may be formulated for quick or controlled release. An organic N,K,P nanofertilizer can be formulated containing an engineered bio- polymer in the form of nano bio-polymers in an amount of about 5-35%bio-polymer, preferably 15-30%, and at least one bioactive compound encapsulated with the nano bio- polymer in a nanoparticle. The bioactive compound includes an organic certified source of N, P and/or K. The engineered bio-polymer can optionally include at least one anchoring and/or targeting group attached to the surface of the nanoparticle. The N, K, P nanofertilizer can be applied after appropriate dilution of 1:900 - 1:400 depending on the plant to be treated. The nanoparticles or can be further cross-linked to form a nanofertilizer gel. The nanofertilizer can optionally include one or more digested carbohydrate compounds in a concentration of about 1%. Suitable digested carbohydrate compounds include but are not limited to molasses, humic acid, polyglucuronic acid and/or pectin. The carbohydrate compounds are digested prior to inclusion in the nanofertilizer using digesting enzymes selected from: pectinase, mannanase, cellulase, xylanase and/or amylase. Optionally, a yeast extract can be included at a concentration of about 10-13% and microelements such as Bo, Fe, Mn, Zn, Co, Cu, Mo, Mg and/or a precursors thereof can be included at a concentration of 0.1%-0.5%, preferably 0.2%. The microelements can be added in their nano form, as a metal salt, or a combination thereof. The micro/nano elements can be cross-linked to the surface of the nanoparticles, cross-linked to the gel, and/or can be added to the nanoparticle solution as a mixture. The size of the nanoparticles can be from 5-1000 nm, and their shape can be spherical, cubic, rods, dimers, trimers, quatramers, rhombic, or a combination thereof. Anchoring peptides can be used to improve the delivery of the bio-polymers and nano bio-polymers into the plant after application, preferably after foliar application. The anchor peptide can have between 10 to 100 amino acids. The mass fraction of the anchor peptide is between 0.2 – 2 mol%. As an example, the anchoring peptide can be selected from a class of anti-microbial peptides including plantaricin A. Plantaricin A (PlnA ; 26 aa) in an amount of 0.45 mol % can be conjugated onto nanoparticles derived from keratin hair extracts. Plantaricin A increases attachment of the nano particles to the surface of the plant leaves as compared to non-conjugated nano particles. Plantaricin A – keratin nano particles remain attached to the leaves, even when the surface of the leaf is washed. Bio-polymers and nano-biopolymers on plant leaves or within the endosomes have been found to show slight agglomeration. Keratin nano bio-polymer delivery systems, produced by ball milling bio-polymers and nano-biopolymers, are very stable between pH 7-9, but tend to agglomerate at lower pH values ~ 5.3. The keratin nano bio-polymers can be strategically prepared at this pH value. When applied to a plant leaf, where the pH is 5.6-5.8, they internalize into the plant without releasing the encapsulated bioactive agent on the surface of the leaf. Disintegration and release of the bioactive agent is achieved enzymatically due to the glutathione inside the cells. In certain embodiments, in order to prevent agglomeration of the bio-polymers and nano-biopolymers, strategic polymeric functional groups such as PEGOH-CPP can be attached to the initial peptide structure. When the PEG moiety has a silyl group or an anti-microbial peptide attached to one end, the resulting delivery system can anchor to the waxy surface of the plant leaves. Handling and management of industry by-products is costly because they require significant space for storage, and management. There are also significant sustainability concerns. However, using the present methods, these by-products can be utilized as raw materials to produce renewable bio-NADES. The resulting bio-NADES (slurry or pure liquids) can then be used in the same pot process to extract other agricultural ingredients from various sources of waste. The one pot method is a platform method, it is multifunctional, and can use NADES, bio-NADES, DES or a combination thereof to extract agricultural ingredients from various types of waste. Various agricultural products can be produced, and they can be presented in liquid, powder and/or gel form. Wool or feather by-products were chosen as a keratin peptide source for the examples because of their low processed quantities as compared to other peptide by- products. Keratin by-products are one of the most abundant bio-wastes. Only a small percentage of keratin by-products are processed to biomass and re-utilized in industries such as cosmetics, pharmaceuticals, animal feed, and agricultural formulations. The low keratin quantities processed vs the waste quantities produced, make keratin by-products a potential threat to the environment. Poultry feathers alone generate about 8.5 billion tons of keratin bio-waste annually, however, only about 40 million tons of keratin bio- waste are processed every year. The remaining keratin bio-waste is dumped, buried, or incinerated producing environmental hazards, pollution, negative effects on human health, and increased greenhouse gas concentrations. The following examples are provided to enable those of ordinary skill in the art to make and use the methods and formulations of the invention. These examples are not intended to limit the scope of what the inventor regards as the invention. Additional advantages and modifications will be readily apparent to those skilled in the art. EXAMPLES: Example 1 Biomass Extraction using natural eutectic solvents (NADES) The hydrogen bond donor (HBD) is chosen for DES/NADES synthesis based on their acidity and the viscosity of the final DES. The strength of the hydrogen bond between HBA:HBD influences the potency of the DES/NADES, and increases with their acidity. Oxalic acid is preferred as a HBD, based on its strong acidity. Natural acids such as lactic acid, acetic acid, formic acid, and citric acid can also be used. Choline chloride is dried under vacuum a.t 80°C for 48 hours before use. The oxalic acid (HBD) was mixed the choline chloride at a preferred molar ratio HBD: ChCl of 0.5: 1 in an iodine flask, avoiding any contact with air moisture, and heating at 80°C, until a homogenous and transparent liquid is obtained. The solid waste, 2 g of ground poultry feathers, is dissolved in 200 ml ChCl-OA (DES/NADES) at a weight ratio 1:1, and mixed for 6 hours at a temperatures of 60 °C. The extract is filtered, and the supernatant precipitated with ethanol. The precipitate is then filtered and frozen for 3 h. The resulting keratin peptide extracts have a molecular weight of about 12 KDa, about 96% purity and a 98% reaction yield. The DES and NADES can be reused by evaporation of the ethanol in a high vacuum pump at 45°C. . Example 2 One Pot Process for Biomass Extraction, Production of Nano bio-polymers and Their Encapsulation with Bioactive Compounds The peptide can be extracted following the procedure of Example 1 and then re- dispersed in an aqueous solution with a pH between 6-8 at a concentration between 0.5- 5%.The resulting mixture is ultrasonicated at 800W for 10-30 min to produce the peptide- based nanoparticles. A particle size between 1-1000 nm can be obtained by controlling the sonication time, the concentration of the extracted peptide and the pH. To obtain nano bio-polymers between 100 nm to 150 nm, the pH is 7, the sonication time t=10 min, and the extract concentration is 1%. In the same reaction, the nano bio-polymers can be encapsulated with a bioactive agent by introducing the bioactive agent into the mixture at a nano biopolymers: bioactive agent mass ratio of 50:1 (w/w), and the mixture is subjected to further sonication for another 10-30min. The peptide extracts obtained according to the procedure of Example 1, are subjected to sonication without separating the ChCl-OA liquid to produce the nano bio- polymers in a one pot synthesis. Ultrasonication was applied at pH=7 for 10 min to produce keratin nanoparticles of 100 nm. The keratin nanoparticles were encapsulated with organic potassium and phosphorus by sonicating the mixture for another 10 min after adding the potassium and phosphorus. The encapsulated nanokeratin can be used in an agricultural formulation without further processing or it can be purified by centrifugation. The resulting encapsulated nanokeratin having about 18.96 μg/mg to about 22.75 μg/mg potassium per milligram of particle. Example 3 Encapsulation of Nano bio-polymers Obtained by Ultrasonication using pH Controlled Swelling The nano bio-polymers of example.2 (after extraction and sonication) are isolated either by precipitation and filtration or by centrifugation, then added to a solution that contains the bioactive agent, under a specific pH. The pH is chosen so that the nano bio- polymers swell, and diffusion of the bioactive agent into the nano bio-polymers occurs, followed by a pH adjustment to shrink the encapsulated nano bio-polymers. When using the encapsulation by taking advantage of its swelling capability, the loading is performed at very acidic pH-3 or very basic pH-9 where the keratin nanoparticles are highly swollen. The nanoparticles are placed in the swelling solution containing the bioactive agent and continuously stirred for 2 hours. After, the loading solution pH is increased to about pH 6, the nano bio-polymers collapse and entrap the loaded bioactive agent within the polymer network. Using this procedure, the amount of potassium encapsulated is between 25.06 and 39.15 μg/mg particles. Note that co-encapsulation can be also performed using both encapsulation methods. Example 4 Synthesis of Nano bio-polymers using a crosslinking method 100 mg of powder keratin extract made according to Example 1, are diluted with 2 ml of deionized water and then mixed with 8 ml of absolute alcohol or a mixture of AOT/1- HP/Isooctane (25%/62.5%/12.5%). To this, 1 μl of 8% glutaraldehyde, divinyl sulfone (DVS) or 1,4-butanediol diglycidyl ether (BDDE) is added. The mixture is stirred using a magnetic stirrer at 40 rpm for 24 h. The stirred content was then centrifuged by cooling centrifuge (Remi) at 10,000 rpm for 20 min. The supernatant is discarded, and the pellet is collected. A lyophilization process is performed to obtain the keratin nanoparticles. The resulting nanoparticles and nanogels can be encapsulated according to the procedure of Example 3. Example 5 Production of Chitosan Nano bio-polymers A chitosan extract with a concentration of 35%, is diluted to 0.1% and the pH is adjusted to 5.5 while simultaneously mixing with a TPP solution at a concentration between 0.02 -0.05 % at pH- 7.5 and a bioactive molecule at a concentration between 0.03 to 0.08 %, using a programmable pump. The volumetric flow rates from 20-500 mL min_1 Example 6 Hydrolysis of Waste By-products Using NaOH in the Presence of Microelements 100 grams of solid waste protein (bath ratio 1:1) are mixed with 100 ml of alkaline solution at a concentration of 5-20 %. The solid waste protein is hydrolyzed by shaking or stirring the solution in the presence of 0.1 to 1 wt% concentration of microelements at to 60 °C between 30 min to 4 hours. The solution is neutralized to pH= 7.5 and mixed at room temperature for another 20 min. Peptide chelates of Fe 3+ can be prepared by using the ammonium sulfate solution of iron. Peptide chelates of Zn2+ can be prepared using Zinc Chloride as a source of Zn2+. Peptide chelates of Mg2+ can be formed by addition of manganese sulfate. Peptide chelates of Cu 2+ can be formed by adding copper sulfate. The pH of the solution is adjusted to pH=6.5 to 8, preferably at 7.5 using sulfuric acid. The solution containing the peptide chelate compounds can be used directly as a fertilizer or it can be used as a fertilizer raw material subject to further processing. Example 7 Surface Functionalization of Bio-polymers and Nano Bio-polymers The extracted bio-polymers and nano bio-polymers according to the Examples 1- 6 can be further functionalized by using covalent functionalization or a covalent reaction using a linker. Covalent functionalization of an extract with a desired molecule can be achieved using intermediate linkers, wherein the targeted groups of the extracts are either the amines (NH2), carbonyl groups (COOH), hydroxyl (OH), sulfhydryl (SH), or aldehyde (CHO), or azide (N 3 ) or a combination thereof. Keratin possesses a number of pendant functional groups such as -NH2, -COOH, -SH and –OH. The amine functional groups of keratin bio-polymers or nano bio-polymers and the carboxyl functional groups of a desired compound (e.g. a bioactive agent, a polymer- acrylate or methacrylate, or 2-carboxyethyl acrylate) can be cross-linked. The components in a molar ratio 1:4:4 of an aqueous extract of keratin (12 KDa), a COOH- terminated functionality (ex: polymer or co-polymer (methacrylic acid)), and 1-ethyl-3-(3- dimethylaminopropyl)carbodiimide hydrochloride (EDC) are mixed at pH-4.5 and reacted for 1 h. The resulting cross-linked keratin is precipitated using ethanol and then freeze- dried to obtain the powder keratin-methacrylic acid. Any molecule having a COOH group can be attached to keratin or another peptide having a free NH2 group, using this method. Crosslinking between the amine functional groups of keratin and a carboxyl functional can be carried out using thiol click chemistry utilizing succinimidyl 4-(N- maleimidomethyl)cyclohexane-1-carboxylate (SMCC) as the cross-linker. An anchor- peptide can be bound at one end (or subsequently added) resulting in a keratin-anchoring peptide functionality. An eGFP-anchor-peptide fusion protein, (0.45 mol % Plantaricin A (PlnA ; 26 aa)) can be conjugated onto the keratin bio-polymers and nano bio-polymers of Example 1-6, and the resulting Plantarcin-bio-polymers and Plantarcin-nano bio-polymers can be applied to a plant by foliar application. Plantarcin A increased the attachment of the bio- polymers and nano bio-polymers to the surface of a plant leaf and remained attached to the leaves even when the leaf surface was washed. The keratin functionalization with 0.1 to 0.9 wt.% eGFP-anchor-peptide fusion protein is produced as follows: 20 g keratin extracts of Example 1- 6, were dispersed in a aqueous solution of pH 7.5, and mixed with SMCC at a concentration of 1mg/ml -10 mg/ml, preferably 1.5 mg mL -1 , 20x equivalent with respect to the peptide and stirring for 15 min. Subsequently, the eGFP-anchor- peptide fusion protein (0.1 mg, MW: 32314.7 g mol -1 ) was added and the mixture was stirred for 2 h at room temperature, followed by precipitation using ethanol, and freeze dried overnight. The keratin of Examples 1-6 are functionalized with biomolecules containing-NH2, and the reaction is carried out between molecule-NH2 and keratin-COOH. The reaction requires the activation of the carboxylic groups of COOH, using 1-Ethyl-3-(3- dimethylaminopropyl)carbodiimide (EDC) in the presence of N-hydroxysuccinimide (NHS). Keratin-COOH and the NHS are dissolved in distilled water and the pH is adjusted to 5.4 by an addition of 2 M NaOH solution. After 15 minutes of constant stirring, the EDC solid was added slowly to a molar ratio EDC/NHS/COOH of 10:4:1. The pH was kept constant at 5.4. Next, the peptides were precipitated using ethanol. The resulting compounds can be freeze dried, oven dry or dispersed in an aqueous solution at a preferred concentration. Using the EDC/NHS coupling chemistry, a variety of peptides can be cross-linked. The engineered keratin of Examples 1-6 are formed by dissolving the keratin 1 mg/mL solution in an aqueous solution with a pH between 4.5-7.5. Depending on the amino acid composition of the keratin polypeptide, the solubility pH will be different. Then, SMCC is added at a concentration between 1mg/ml -10 mg/ml and the reaction is mixed for at least 3 hours. Optionally, the SMCC linker can contain a bioactive compound either an agricultural active compound, a polymer or any desired compound having an amino group. The amino-terminated- compound can be added to the SMCC linker at a molar ratio 1:10 in 100 mM KH2PO4 buffer at pH 7.2 and mixed for at least 1 h. The resulting conjugate is then purified. The resulting conjugate can be a keratin chain or nanoparticles depending on the amino terminated compound. Covalent reactions using a linker to hydroxyl (OH) functionalities; a linker to aldehyde (CHO) functionalities or using a linker to azide (N3) functionalities can be performed on the extracts of Examples 1-6. A combination of surface functionalization can be performed as well. Example 8 One Pot Green Process for Producing an Organic Keratin Smart Delivery NanoFertilizer, NanoPesticide, NanoHerbicide, NanoFungicide or Nanoinsecticide, or a Multimodal NanoFormulation using renewable bio-NADES. The process comprises the following steps: 1) making the bio-NADES; 2) extracting the keratin from feathers; 3) engineering the keratin using ball milling to nanoscale to produce nanofertilizers; and 4) adding bioactive compounds such as growth regulators, pesticides, herbicides, fungicides, or insecticides to step 3, to encapsulate them inside a keratin nanoparticle. A combination of two active ingredients can be added to step 3, and co-encapsulated. The resulting formulation will act as a dual modal formulation. Up to ten active ingredients can be added at step 3, to produce a multifunctional formulation. Step 1. Making the bio-NADES: 30 kg of sugar cane bagasse (or molasses) can be ground and pretreated in a 100 L reactor in acidic media using ballmilling at 500 rpm for 2h at 60 0 C, pH=4. Next, half of the pretreated bagasse slurry, 50 L is placed in a fermentation reactor and incubated with 2% urea, 3% methanol and A. niger spores, 10 7 spores/g of dry material for 4 days. The fermentation reactor lid is punctured to facilitate and optimize oxygen penetration, at 75% moisture, as well to provide proper ventilation of the heat produced during the fermentation process. The remaining pretreated bagasse, 50 L is mixed with the fermenting half and the reaction is thoroughly mixed with ballmilling for an additional 30 min at 50 0 C. The resulted is the bioNADES. Step 2. In the same pot process, 1 to 10 kg of ground feathers is added to the ball milling reaction resulting in the extraction of keratin and other components from the feathers. The reaction is carried out at 65 °C for 2 hours with a resulting extraction efficiency of 85%. The resulting nanoslurry (100-130 nm) can be used as a nanofertilizer. In order to decrease the nanoparticle sizes, ballmilling can be carried out for an additional 30 minutes. Sonication can be performed at this step for 20 min to produce nanoparticles of less than 100 nm. Step 3. Bioactive compounds having plant growth and protection functions, at a ratio of 0.1-1:10 active compound:keratin can be added after step 2 to produce a NanoFertilizer, or NanoPesticide, NanoHerbicide, NanoFungicide and/or a Nanoinsecticide.

The formulations include (1) keratin or nanokeratin in a concentration between 5-25%, preferably 5%-10%; (2) 1% Molasses; (3) 0.1%-0.5% microelements such as Bo: 0.2-0.3 g/l; Fe: 0.3-0.5 g /l; Mn: 0.4-0.7 g/l; Zinc: 0.5-0.7 g /l; Co: 0.05-0,1 g/l; Cu: 0.2-0.3 g/l; Mo: 0,7-0.9 g/l; and Mg: 1,2-1.5 g/l; (4) P 2 O 5 between 90-100 g/l; (5) urea between 150-170 g/l; (6) K2O between 80-90 g/l; (7) 5 % yeast extracts and preservatives. The pH of the fertilizer is kept to 4 to avoid microbial attacks. A nanocomposite fertilizer of N, K, P, can be prepared which includes 1) Urea encapsulated nanoKeratin 2) P 2 O 5 encapsulated nanokeratin, and 3) K 2 O encapsulated nanokeratin. Optionally, the nanoKeratin composites can be combined with other nanoparticles, such as zinc oxide, copper oxide, iron oxide, titanium oxide, calcium oxide/ hydroxide, hydroxyapatite nanoparticles, nickel, aluminum, silicon, carbon, precursor nanoparticles, or a combination thereof; wherein the other nanoparticles are attached to the keratin, are in the solution, or a combination thereof. Wherein, their concentration and ratio are customized based on the plant needs. The concentration is between 500 ppm to 4000 ppm, but preferably at a concentration lower than 1000 ppm in the final volume. It is preferable that the nanomicroelements be applied at a concentration of 15-20 times lower than the recommended field dosage of their bulk counterparts. The fertilizer formulation includes from 5-75% phosphorus, preferably 55%; 5-55% nitrogen, preferably 25%, and 5-75% potassium, preferably 20%. The nanocomposite sizes can be between 10-1000 nm, preferably between 100-200 nm. Additionally, the nanoparticles can be of different sizes and shapes such as spherical, cubic, rod, rhombic, wires, chains, etc. The nanofertilizer can include a mass fraction of the anchor peptide Plantaricin in an amount between 0.2 – 2 mol%, but preferably 0.45 mol %. An N organic fertilizer is disclosed, comprising 1) 5-25% keratin extracts or nanoKeratin; 2) 2-10% enzyme extracts, and 3) 1-3% Molasses and preservatives. The keratin component can further include Plantaricin A in an amount between 0.2 – 2 mol%, but preferably 0.45 mol % on its surface. The result is a Smart Foliar nano N organic fertilizer with controlled delivery in the form of a liquid with an adjusted pH of 4. The resulting fertilizer can be also converted to powder, by freeze drying or other well know methods. A fertilizer for metal deficiency crops can include the above discussed components and in addition, metal precursors of Bo, Fe, Mn, Zn, Co, Cu, Mo, Mg, or a combination thereof. The loading of the metal ions is performed by loading of the keratin bio-polymers and/or nanokeratin bio-polymers with metal ions, using a 4-fold excess (volume with respect to the keratin mass) of metal ion solution, under acidic pH~2. Next, the mixture was diluted 4x and stirred at room temperature for 4 hours. Subsequently, the solution was centrifuged at 5000 rpm for 30 min to separate the nanokeratin or keratin from the unabsorbed ions. Nanoparticle precursors of Bo, Fe, Mn, Zn, Co, Cu, Mo, Mg, or a combination thereof can be absorbed. Their concentration and ratio are customized based on the plant needs, are between 500 ppm to 4000 ppm, preferably at a concentration lower than 1000 ppm in the final fertilizer volume. Example 10 A N, K, P organic fertilizer gel can be produced in a one pot synthesis. The fertilizer includes: 1) Keratin bio-polymer gel and nanokeratin gel, at a concentration of 5-35%, but preferably 5% -10%, that was synthesized according to the above examples: using NADES for extraction, and then subsequently adding nitric oxide to crosslink the keratin and form gels. The resulting nanokeratin gels are 50 nm. Further, the bioactive compounds N, K, P are absorbed into the gel. The N, K, P composition and ratio is selected from a range between from 5-75% phosphorus, but preferably 55%; and 5-55% nitrogen, but preferably 25%, and 5-75% potassium, but preferably 20%. In a further embodiment, microelement and nanoelements are added using the absorption method described above. The one or more additional nutrient can be a part of the composition that comprises the nanoparticle or can be a part of the nanoparticle, or engineered peptide, or their gels. Example 11 A seed priming or seed coating composition can be synthesized using a dry chemical method. First, keratin was extracted using a Urea:K2SH system that was formed by adding 1.2 g of Urea, 74 mg of K2SH and 10 ml of water and reacting it at 80 ° C until a white liquid was formed. Then, 130 g of feathers were added to the liquid and the extraction was carried at 80 ° C for 1.5 hours. The resulting keratin size was of 10 KDa. Without any further purification, microelements in the form of oxides or chlorides of Ca, Mg, Mn, or Zn in a percentage of 2-4% of the total keratin were added to the composition. Anti-freeze components and Choline chloride-EG DES of 0.2-1% were added. Gentian violet was added as a colorant in the waxy composition. Finally, the seeds were immersed in the composition in a volume ratio of 0.2 ml/seed, having a peptide concentration of about 1-5%. Figure 3R shows the seeds before and after coating. In order to improve the preservation, a second protection layer can be added on the top of the active composition. The second protection layer can be for example, gum Arabic, clay, polyacrylic, PEG, or starch or a combination thereof. Example 12 Dicamba herbicide can be encapsulated using the dry synthesis method. Dicamba and keratin were added in a ratio of 1:3 with the reaction initiated using 5% water, and the subsequent addition of a functional linker, 5% oleylamine, followed by precipitation of the resulting waxy product using different pHs and buffers (see Figures 3A-D). Precipitation using Tris buffer 10 mM, at pH 7 (Figure 3A), produced 100 nm spheres vesicles; at pH 6.5 (Figure 3B), produced spheres of about 100 nm; at pH 4.5 (Figure 3C) produced nanoparticles around 200 nm; at pH 3.5 (Figure 3D) produced polydispersed nanoparticles of different sizes; at pH 8 (Figure 3E) produced nanoparticles of around 50 nm in size; at pH 10, the nanoparticles seemed to have an undefined shape. Other solvent precipitants at pH 7 were also tested and their impact on size and shape are shown in Figures 3G-J as follows: methanol (Figure 3G), Tap Water (Figure 3I); Acetone, (Figure 3H); Acetone + Methanol 1:1 (Figure 3J). Different nanoparticle shapes and sizes were produced by using different fatty functional linkers such as calcium stearate, iron stearate, and others. The calcium stearate butterfly shape is shown in Figure 3M, the rice shape is shown in Figure 3N and the sphere shape is shown in Figure 3N’. The dry chemistry functional linker can also be a polymer. Representative TEM images of PEI are shown in Figures 3O-P. Example 13 Drug loading capacity using both metal encapsulation and the dry polymer method was evaluated. The encapsulates were dialyzed for 1 day to remove unstable adsorbed drug. Subsequently, the free drug was measured by UV spectrometry. Further the dialyzed delivery systems were freeze dried to obtain a pure encapsulated delivery system. The drug loading content (LC%) and drug encapsulation efficiency (EE%) were calculated according to the equations presented in Figure 7. The most effective drug loading was performed at pH 7, with about 98% encapsulation efficiency. 91 % loading efficiency was obtained at pH 6.5. Example 14 A keratin-herbicide (dicamba) pH control delivery system was produced. The system reduces volatilization of dicamba, confers increased efficiencies, reduces the amount of herbicide application, reduces human exposure, and reduces toxicity. The delivery system was encapsulated using the dry method, keratin:dicamba ratio 1:10 weight ratio, initiated with 10% water and 5% oleylamine. The waxy clay was precipitated by the addition of tap water having 0.1 % Tween 20, at pH 7. The resulting nanoparticle delivery systems were about 100 nm in size and were observed by the appearance of a white milky colored solution. The TEM images of the resulting nanoparticles are shown in Figure 8A. The pH controlled release was demonstrated by TEM imaging and Z-potential. The nanoparticles were centrifuged and exposed to different water solutions for four hours. Figure 8B shows the results at pH 6.5, the nanoparticles were observed to agglomerate and leach in small amounts. Figure 8C shows the delivery system exposed to pH 5.4, dark patches can be seen along with half full vesicles surrounded by leached herbicide. Figure 8D shows the results at pH 3.5, the nanoparticles swell to 1-2 micron from their initial 100 nm, and the herbicide leach is accentuated and appears as big grey patches all over the grid. In addition, a time release profile of dicamba at pH 5.4 and pH 7 was assessed and the results are presented in Figure 7 middle panel. There was a complete release of Dicamba at pH 7 in 45 days; and a complete release of dicamba at pH 5.4 in about 70 hours. Example 15 The delivery systems according to the present invention can be used for an enzymatically controlled release. In plants, glutathione is found in the cytosol, endoplasmic reticulum, vacuoles, mitochondria, chloroplasts, peroxisomes, and the apoplast (Noctor and Foyer 1998). For example, in tobacco mesophyll cells, GSH is distributed as 76%, 17%, and 7% in chloroplasts, vacuoles, and the cytoplasm, respectively (Berthe-Corti et al.1992). Some plant species (e.g. soybean, pea, peanut) do not primarily contain GSH; instead, they contain another thiol called homoglutathione (γ-glutamylcysteinyl-β-alanine), which functions in a similar way to GSH and shows the same redox reaction. Keratins are known to be GSH and HGSH responsive, by their exposure the nanoparticle system will deliver the encapsulated compounds in an enzymatically control manner. The enzymatic release profile of the nanoparticles was evaluated using the dialysis method at 37 °C. The nanoparticles were exposed to different concentrations of GSH, 10mM and 50mM, and at certain times, the dialyzed encapsulate was tested by UVspectrometer. The herbicide atrazine combined with gentian violet was encapsulated using the dry method at a weight ratio of keratin:atrazine of 1:15 and a weight ratio of keratin:GV of 1:0.5. The water quantity was 5% in each and the functional molecule was fatty hexylamine. The control release properties were stimulated both enzymatically via glutathione (GSH) 10 mM, and by pH as shown in Figure 7, lower left panel. A complete release at pH 7 when they were stimulated enzymatically with 10 mM GSH in 500 h vs only about 30% release at pH 7 with no enzymatic stimulation, and 15 % release at pH 7.4. The delivery systems were shown to have a GSH concentration dependent release profile with a complete release of the drug in 300 h when exposed to 50 mM GSH. The nanoparticles were also shown to be responsive to sonication (See Figure 7, bottom right panel). Showing the loss in in color intensity with the release of the GV. Example 16 Using a delivery system, an active agricultural compound, such as a nutrient, herbicide, pesticide, peptide, RNA, DNA, a complex of enzymes with DNA or RNA, or a combination thereof can be complexed with the bio-polymer and delivered to a plant. A delivery system of keratin extracted from feather waste was encapsulated with an herbicide and applied to a pepper plant both by foliar and root application. Figures 9A-O show the pepper plants treated with the delivery systems. Pepper plants treated by foliar application with NPs- Atrazine-FITC are shown in Figures 9A-C; pepper plants treated with NPs-Dicamba-FITC are shown in Figures 9D-F; and pepper plants treated with NPs- FITC are shown in Figures 9G-I. Root application with NPs- Atrazine-FITC are shown in Figures 9J-L (cross section of leaf) and Figures 9M-O (cross section of root). In all cases the green florescence indicates the internalization and distribution of the nanoparticles inside the plant. The herbicides first tagged with a florescent molecule, floresceinisocyanate (FITC) using the known EDC/NHS coupling. DCC (1.62 mmol) was dissolved in DMF (25 mL) and added dropwise to a solution of Dicamba (3.24 mmol) and NHS (3.24 mmol) in DMF (25 mL) under nitrogen atmosphere with ice-cooling. The mixture was stirred at low temperature overnight to form a white precipitate followed by filtration. Appropriate amounts of the filtrate were added to a solution of 2 mg/ml of FITC at pH 8.0. The herbicide conjugated FITC and FITC alone were then encapsulated into the keratin bio-polymer to form a florescent delivery system. Example 17 The delivery systems keratin-transferrin-FITC, and NPs-RNA complex were synthesized in a weight ratio of 1:0.5, keratin: transferrin, and 5:1 keratin: RNA, followed by the addition of 5% water and 8% calcium-stearate modification. The waxy product was precipitated to nanoparticles by using 10 mM Tris pH 8. The transferrin and RNA was modified with FITC using EDC/NHS coupling. The delivery system was applied to the plant by foliar application. Figures 9P-R show the TEM images of the complex, keratin- transferin (Figure 9P left corner), Keratin-RNA (Figure 9R left corner), along with their internalization into the plant (Figure 9P – transferrin complex internalization, Figure 9R - Keratin-RNA internalization). The internalization of the complex is represented by the florescence.
