FLUORESCENT PARTICLE COMPRISING GOLD NANOPARTICLES AND METHOD FOR MANUFACTURING SAME

摘要

Provided are a fluorescent particle and a method for manufacturing same. The fluorescent particle comprises: gold nanoparticles; a silica shell covering the gold nanoparticles; and lanthanide group complex particles dispersed in the silica shell. Each of the lanthanide group complex particles may comprise: a lanthanide group ion; a ligand which bonds with the lanthanide group ion and comprises phosphorus; and a ligand which bonds with the lanthanide group ion and has a beta diketone functional group. The fluorescent particle is observable with the naked eye and can emit light when irradiated with ultraviolet light. The fluorescent particle can be used for detecting and analyzing biomaterial samples.
