Abstract
Disclosed are fluorescent substance-containing silica nanoparticles containing a fluorescent substance therein featured in that the surface of the silica nanoparticles is coated with a material having a bulk refractive index of from 1.60 to 4.00. The invention can provide fluorescent substance-containing silica nanoparticles excellent in long term storage stability and a biosubstance labeling agent employing the same.
