It was shown first that solutions of nongelable polysaccharides, including such practically important ones as chitosan, hyaluronate, and cyclodextrin, can be gelled by generating silica in situ via sol-gel processing. This could be done owing to a no

The synthesis of hybrid organic–inorganic nanocomposite materials containing biopolymers by the sol-gel processing is often faced with severe difficulties owing to their poor compatibility with the common precursors. The problem was solved when tet

Tetrakis(2-hydroxyethyl) orthosilicate (THEOS) introduced by Hoffmann et al. (J. Phys. Chem. B., 106 (2002) 1528) was first used to prepare hybrid nanocomposites containing various polysaccharides and immobilize enzymes in these materials. Two differ

The effects of shear flow on the lecithin organogels consisting of reverse polymer-like micelles have been investigated by dynamic rheology. It was established that the shear effects depended on the molar ratio of water to lecithin that determined th
