                         base-catalyzed hydrolysis and polycondensation of tetraethyl 
                         orthosilicate (TEOS) in an alcoholic medium with the careful 
                         variation of the concentrations of water, ammonia and TEOS. In 
                         this study, we investigated the influence of experimental 
                         parameters on the average size of nanoparticles by means of a 
                         multivariate statistical analysis using a factorial design to 
                         create one model to predict particle size in function of 
                         experimental conditions. This model predicted that it is possible 
                         to synthesize silica nanoparticles with size in the range from 17 
                         to 333 nm, according to the chosen condition for the amount of 
                         water, ammonia and TEOS. It was observed that only the molar 
                         amount of NH3, the molar amount of H2O and the effect from 
                         interaction between molar amount of TEOS and H2O were significant. 
                         Subsequently, surface modification of the colloidal silica was 
                         performed in situ using the coupling agent
