LABEL SILICA NANO-PARTICLE FOR IMMUNO-CHROMATOGRAPHY REAGENT, IMMUNO-CHROMATOGRAPHY REAGENT, TEST STRIP FOR IMMUNO-CHROMATOGRAPHY USING IT, AND FLUORESCENCE DETECTION SYSTEM FOR IMMUNO-CHROMATOGRAPHY

摘要

PPROBLEM TO BE SOLVED: To provide a label silica nano-particle for immuno-chromatography to which various hues, fluorescent wavelengths or the like can be imparted by changing a label material included, and which does not have a dark color by aggregation or the like; to provide an immuno-chromatography reagent which is formed by modifying the surface of the silica nano-particle with a material recognizing an analyte; to provide a test strip for immuno-chromatography which is formed using the immuno-chromatography reagent; to provide a fluorescence detection system for immuno-chromatography using a fluorescent material as the label material. PSOLUTION: The label silica nano-particle for the immuno-chromatography reagent comprising a silica nano-particle formed containing a label material is characterized by the label silica nano-particle of which average particle diameter is 20-600 nm, and of which surface is modified with the material recognizing an analyte, while characterized by the label material which is a fluorescent material or light absorption material.
