界面活性剤混合系で形成するベシクルの機能性材料への応用

Vesicles with bimolecular membranous structure have been used as a drug carrier in drug delivery systems, a biomembrane model, and so on. Recently, vesicles have also attracted attentions with a view to application for cosmetics and foods industries since they can not only entrap water–soluble substances in their core, but also solubilize oily substances in the bilayer membrane. In this review article, photochemical control of vesicle formation using photoswitchable surfactants (azobenzene–modified surfactant, cinnamic acid–modified surfactant) and photochemical release control of encapsulated aqueous model drug are described. In addition, preparation of silica hollow nanoparticles using vesicles formed by cationic surfactant mixture as a structure directing agent is also introduced.
