Abstract

A novel type of amino functionalized core-shell Ru(bpy)3-doped silica nanoparticles was synthesized using a simple and effective approach of reverse microemulsion. The nanoparticles were characterized by transmission electron microscope, fluorescence spectra, UV-Vis spectroscopy and tests of photostability and dye molecular leakage. It was found that the nanoparticles exhibit excellent fluorescent properties such as extremely bright, highly photostable and chemicalstable. Furthermore, the nanoparticles utilized as a fluorescent marker applying in fluorescent immunoassay of mouse IgG were studied and desired results were obtained.
