This chapter is important as it provides a comprehensive understanding
of the various classifications of liposomes, which are essential for designing effective
drug delivery systems. Size and lamellarity liposome, composition, and preparation
methods are the factors that determine the classification of liposome. The chapter
emphasizes how these classes affect the size of liposomes, stability, and function, with
particular attention to their use in drug administration.
Keywords: Liposome size, lamellarity, PEGylation, ligand-targeted liposomes, multifunctional liposomes, drug delivery.
