Syntheses and Characterization of Silica Nanoparticles Grafted with Selected Heterocyclic Derivatives

Sol-gel process has been used to synthesize amino functionalized silica nanoparticles by using gelator precursor tetraethylorthosilicate (TEOS) as well as tetramethoxyorthosilicate (TMEOS) and surface modifier, 3-Aminopropyltriethoxysilane, 3 Aminopropyltrimethoxysilane, separately. Sol-gel methodol...
