Title:
SIMPLE PREPARATION METHOD FOR AND APPLICATION OF ULTRA-SMALL SELENIUM NANOPARTICLE-LOADED METAL FRAMEWORK COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2023/082216
Kind Code:
A1
Abstract:
An ultra-small selenium nanoparticle-loaded metal-organic framework composite, and a preparation method therefor and an application thereof. The method comprises: adding PEG 400 and selenium powder into a beaker, and stirring after sonication to uniformly disperse the selenium powder in the PEG 400; transferring the beaker to a magnetic stirrer, stirring while heating, naturally cooling after reacting for a certain period of time, transferring into a centrifugal tube for centrifuging, obtaining a supernate after centrifuging, and finally obtaining PEG-SeNPs; and preparing a selenium nanoparticle-loaded metal-organic framework composite by using raw materials comprising the PEG-SeNPs and a metal salt solution, and suspending the selenium nanoparticle-loaded metal-organic framework composite in a buffer solution. The ultra-small selenium nanoparticle-loaded metal-organic framework composite has an effect of effectively scavenging free radicals, and good oxidation resistance, and can effectively reverse damage caused by oxidative stress, and relieve brain damage caused after cerebral ischemia reperfusion.
