Organic–inorganic hybrid particles with complex hollow structures were prepared simply by the gelation of trimethoxylsilyl groups in the preformed self-assembly of PEO-b-PTMSPMA in DMF/water solution. Inside the resulting particle, there are many cavities insulated by cross-linked hybrid bilayers of uniform thickness. Owing to gelation, the morphology of particles is stable against drastic changes in conditions. The potential application of such novel nanomaterials in encapsulation is very promising. For example, as there are many cavities inside the particles, it may be possible to encapsulate functional species into different cavities of a particle for stepwise-release.
