Synthesis and site-specific functionalization of tetravalent, hexavalent, and dodecavalent silica particles

Abstract

Different shapes: Tetravalent, hexavalent, and dodecavalent silica particles were obtained by the growth of the silica core of binary tetrapods, hexapods, and dodecapods, respectively. The surface of the multivalent particles can be regioselectively functionalized, thereby leading to particles with anisotropic geometry and chemistry.

Keywords: colloids; silica particles; surface chemistry.
