Being the silica nano grain the surface qualification with the material which recognizes the production manner of the indicator silica nano grain for the imunokuromato modulo reagent, the production manner of the conjugate pad for imunokuromato modulo, and the use

摘要

PROBLEM 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.;SOLUTION: 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.;COPYRIGHT: (C)2009,JPO&INPIT
