Figure 2
Summary of water-soluble silsesquioxane-based nanoparticles. (a) Water-soluble hybrids synthesized by hydrolytic condensation of hydroxyl-functionalized triethoxysilanes; (b) end-group modifications of the hydroxyl groups of the water-soluble hybrids; (c) cationic hybrids obtained by hydrolytic condensation, followed by quaternization; (d) R–SiO1.5/SiO2 hybrids; (e) R–SiO1.5/TiO2 hybrids prepared by hydrolytic cocondensation of the hydroxyl-functionalized triethoxysilane and metal alkoxides; (f) smart hybrids based on the complexation of the silsesquioxane nanoparticles and weak polyelectrolyte.
