Phospholipid–silica mesophases formed in hydroalcoholic solution as precursors of mesoporous silica

Abstract : Phosphatidylcholine isotropic mesophases are easily formed by membrane fusion in hydroalcoholic solution in the presence of condensating silica. The transformation of lamellar bilayers into a sponge phase proceeds with the increase of the concentration of ethanol until a monodispersed mesoporous silica with surface area 800 m2 g-1 can be formed by calcination. Natural impurities of lecithin favour the formation of the sponge phase.
