Title:

SOLID PHASE CARRIER, AND TARGET OBJECT MEASUREMENT KIT

Document Type and Number:

WIPO Patent Application WO/2024/034561

Kind Code:

A1

Abstract:

A solid phase carrier (1) used to measure a target object includes a substrate (10), and a nano-structure (20) disposed on one surface of the substrate (10), wherein: the nano-structure (20) includes a plasmon excitation layer (21) which is formed from a substance capable of exciting surface plasmon resonance, and which has a nano-structure in which localized surface plasmon resonance is excited through irradiation of light, and a covering layer (25) formed from a substance that does not excite surface plasmon resonance; the plasmon excitation layer (21) has a covered region (21a) covered by the covering layer (25), and a non-covered region (21b) not covered by the covering layer (25); the non-covered region (21b) includes a hot spot in which localized surface plasmon resonance occurs; and a surface of the covering layer (25) has a lower binding affinity with respect to a specific binding substance of the target object than a surface of the plasmon excitation layer (21).
