Liposomes are spherical vesicular systems composed of lipid bilayers.
Among the various novel drug delivery systems, it has been found that the liposomes
follow an advanced technology for the delivery of drugs to the target site. In the present
era, there are various liposomal formulations which are in clinical use. Due to the
extensive efforts of the researchers, there has been tremendous progress in liposomal
technology, i.e., from, conventional vesicles to the 2nd generation liposomes. The
current review article deals with the materials involved in the preparation of liposomes,
techniques for preparation, characterization studies and application of liposomes for
drug delivery.
