Abstract

Silica nanoparticles have proven to be a versatile and useful nanomaterial. This versatility stems from their silanol groups on the surface of the nanoparticles, which can react with various organic molecules such as (3-aminopropyl)trimethoxysilane or (3-cyanopropyl)trimethoxysilane to functionalize the particles. In this study, silica nanoparticles were prepared using the Stöber method and a Piranha cleaning method. These two methods were investigated to see which method produces the optimal number of silanol groups on the surface. Characterization of the silica nanoparticles was achieved using fluorescence spectroscopy and fluorescence microscopy.
