title: Meso-ordered PEG-based particles.
abstract: We report on the formation of meso-ordered hydrogel particles by cross-linking poly(ethylene glycol) diacrylate (PEG-DA) in the presence of surfactants in a confined environment. The results demonstrated that well-ordered mesoporous hydrogel particles having a pore size of about 5 nm could be formed. It is suggested that these meso-ordered hydrogel particles might have unique drug-delivery capabilities.
