This review describes the new aspects of liposome. Liposome has three different types- (1) multilamellar vesicle (MLV), (2) small unilamellar vesicle (SUV), (3) large unilamellar vesicle (LUV) is the best mimetic model for a cell. Each type has its own preparation method, which is discussed in this review.
More stable liposome has been investigated. The lipid derivatives containing the polymerizable groups are synthesized and the liposome prepared with these compounds are photochemically polymerized. The structure of liposome remains unchanged during polymerization. Polymerization of liposome increases the stability.
