What is LIPOSOME ?
Liposomal application as carriers of drugs, gene, and various biomaterials has been widely investigated. Liposomalization of many drugs was revealed to reduce the side effect and to enhance the efficacy of the drugs. Since liposomes are an assembly of non-toxic, biodegradable, and of quite low antigenicity. Furthermore, they may possess various functions associated with biomembranes, such as selective permeability, fusion, special interctions with serum proteins or with cells, and so on. In here, preparation and characterization of such functional liposomes are presented. Liposomal trafficking in living animals, which is important in the use of liposomes as drug carrers, and which was determined by the recently developed method by use of positron emission tomograpy ( PET ), was also mentioned.
