FLUORESCENT MAGNETIC SILICA NANOPARTICLE USING SILANE-LANTHANUM-BASED COMPLEX COMPOSITE AND MAGNETIC PARTICLE, AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a fluorescent magnetic silica nanoparticle comprising a magnetic particle core and a fluorescent silica shell which is formed by cross-linking a silane-lanthanum-based complex composite and a silica precursor, and to a method for producing the fluorescent magnetic silica nanoparticle. The present invention can provide a fluorescent magnetic silica nanoparticle which is used for fluorescence immunoassay and has highly sensitive fluorescent characteristics, has improved chemical stability, and allows easy dispersion of a particle in an aqueous solution and easy collection thereof.
