The design of siloxane-based nanoparticles is important for many applications. Here we show a novel approach to form core-shell silica nanoparticles of a few nanometers in size through the principle of "dispersion of ordered mesostructures into single nanocomponents". Self-assembled siloxane-organic hybrids derived from amphiphilic alkyl-oligosiloxanes were postsynthetically dispersed in organic solvent to yield uniform nanoparticles consisting of dense lipophilic shells and hydrophilic siloxane cores. Insitu encapsulation of fluorescent dyes into the nanoparticles demonstrated their ability to function as nanocarriers. Self-assembled hybrid nanoparticles: A new type of oligosiloxane precursor self-assembles into reverse-micellar mesostructures, which can be transformed to nanoparticles with a siloxane core and an organic shell by dispersion in nonpolar organic solvents.
