摘要：

In this study, the synthesis of monodisperse gold-organosilica core-shell particles was achieved by base-catalyzed cocondensation of tetraethoxysilane and organotriethoxysilane precursors in the presence of surface primed Au sol. Subsequent overgrowth of the inorganic-organic phase by surface-directed cocondensation was successful in producing organosilica shells with covalently linked phenyl, allyl, mercapto, amino, cyano, perfluoro, or dinitrophenylamino moieties.
