A new delivery system has been developed that combines liposomes and silica nanocapsules. It was found that in the presence of cationic unilamellar liposomes, silica nanocapsules are instantly coated with a lipid bilayer. In contrast, cationic stealth liposomes modified with polyethylene glycol can adsorb on the surface of silica to form multi-liposomal composites in which the liposomes remain intact.
