Secret chambers: Organic–inorganic hybrid nanoparticles (see picture) with a complex hollow structure were prepared by the self-assembly of a reactive block copolymer, poly(ethylene oxide)-block-poly[3-(trimethoxysilyl)propyl methacrylate], in DMF/water. Within these hybrid large-compound vesicles, several cavities are separated by crosslinked hybrid bilayers of uniform thickness.
