FLUORESCENT SEMICONDUCTOR MICROPARTICLE ASSEMBLY, FLUORESCENT LABELING AGENT ASSEMBLY FOR BIOLOGICAL SUBSTANCE, AND BIOIMAGING METHOD AND BIOLOGICAL SUBSTANCE ANALYSIS METHOD USING THE ASSEMBLIES

摘要

Disclosed is a fluorescent semiconductor microparticle assembly comprising at least three kinds of fluorescent semiconductor microparticles with an average particle size of from 1 to 10 nm, having the same chemical composition, a different average particle size and a different emission maximum wavelength in the emission spectra, wherein a standard deviation of emission intensity in each of the at least three kinds of fluorescent semiconductor microparticles is not more than 15%.
