Notes:
The core-shell structure of dye-silica nanoparticle has been prepared. The dye-silicananoparticle can be used as a substitute of fluorescent dye for bio analysis. The hybrid organicinorganicnanoparticle was prepared by sol-gel process using organic modified silane as the couplingagent for flourescent dye and silica. The size of the particle was about 50 nm, which was measured byDLS and confirmed by SEM photograph. The fluorescent dye (fluorescein-5-maleimide) was reactedwith (3-mercaptopropyl) trimethoxy silane to produce dye-silane compound, followed by the sol-gelreaction with tetraethoxysilane(TEOS) and water to produce core-shell structure. The fluorescentspectrum showed that the fluorescent intensity of dye-silica nanoparticle was higher than that offluorescent dye
