摘要：

We have prepared a novel organic-inorganic hybrid vesicle "Cerasome", which has a silica-like structure on its vesicular surface. A newly synthesized compound bearing a triethoxysilyl head and a dialkyl tail were dispersed in water under various pH conditions. The cerasome was obtained most efficiently at pH 3, where a gradual and stepwise process of hydrolysis on the triethoxysilyl head did not disturb vesicle formation. In a dried sample, TEM observation revealed formation of a multivesicular assembly.
