Abstract

Abstract Liposomes are vesicles in which an aqueous volume is entirely surrounded by a phospholipid membrane and their size can range between 30 and 50 nm up to several micrometers. Liposomes serve as a drug delivery system because of their versatile structure and because they are nontoxic, nonimmunogenic, and fully biodegradable. This chapter focuses on basic characteristics and applications of liposomes, their fate after in vivo administration by different routes, and other possible routes for in vivo administration of liposomes.
