Chitosan/Silica Hybrid Nanogels by Inverse Nanoemulsion for Encapsulating Hydrophilic Substances
Hybrid chitosan/silica nanohydrogels are prepared by combining ionic gelation of chitosan in a nanoemulsion system with a sol–gel process for incorporation of silica. The efficiency in entrapping a hydrophilic model substance, erioglaucine disodium salt, and the retardation in the release behavior due to the presence of silica offer a suitable material
