Abstract

A detection method for a specific biological substance uses, as a color former, fluorescent substance-encapsulated nanoparticles which have biological substance-recognizing molecules. The biological substance-recognizing molecules specifically recognize a specific biological substance. The biological substance-recognizing molecules are bonded to the surface of the nanoparticles. Nanoparticles encapsulating no fluorescent substance are used as a blocking agent for preventing the fluorescent substance-encapsulated nanoparticles from being non-specifically adsorbed on a biological substance other than the specific biological substance.
