A panoscopic approach for governing the size of Stöber silica particles over a wide length scale, from tens of nanometers to several microns has been suggested. Low-size particles (10–400 nm) are obtained by changing the silica precursor, mid-size particles (0.4–0.7 mm) are synthesized with variation of ammonia concentration, large particles (up to 4 mm) are made by successive growth method.
