A novel method for synthesis of silica nanoparticles ...
Sep 01, 2005· The monodisperse uniformsized silica nanoparticles were prepared by hydrolysis of TEOS in ethanol medium in the presence of ammonium hydroxide. Fig. 1 is a schematic diagram of the synthesis of silica particles and homogeneous samples were prepared by the following procedure. First, ethanol was taken and kept in a sonication bath.
