摘要：
Silica nanoparticles (SiO2 NPs) for biomedical applications have been prepared by using a facile modified Stober-synthesis. Potassium borohydride (MILL) has been introduced in the synthesis procedure in order to control NP size. Several samples have been prepared varying tetraethylorthosilicate (TEOS) concentration, and using different process conditions (temperature, reaction time and atmosphere). In order to study the influence of the process conditions on the NP size, morphology and properties, several characterization techniques were used. Size and morphology of the as-prepared SiO2 NPs have been studied by using Transmission Electron Microscope (TEM) and Dynamic Light Scattering (DLS) techniques. Structural characterization was carried out by X-ray powder diffraction. To investigate the SiO2 NP fluorescence emission properties the fluorescence spectroscopy was also used.
