Synthesis of fluorophore-doped silica nanoparticles using stober method / Nurul Basyeerah Naharazmi

Fluorophore doped silica nanoparticles were successfully synthesized using Stober method. In this method, temperature and curing time serve as constant variable and the concentration of dye which is the mixture of fluoresceine, APTES and water were taken as manipulated variable. The process inclu...
