Background: During past decades, liposomes have emerged as efficient carriers for drugs,
diagnostics, vaccines, nutrients and other bioactive agents. Liposomes, the spherical vesicles consisting
of phospholipids bilayer have the ability to encapsulate both lipophilic and hydrophilic drugs. Extensive
studies have been done in the past for investigating a number of drugs and genes for controlled release
with liposomal formulation. Liposomes have also been investigated for their use in cancer treatment.
Liposomes offer various advantages because of their biocompatible, biodegradable, nontoxic and
Methods: Liposomes have cell-specific targeting with important applications in the fields of nanotechnology
like cancer therapy, diagnosis, gene delivery, cosmetics, agriculture and in food technology.
They are prepared by various methods like sonication method, ethanol injection method, lipid film hydration
method, micro-emulsion method.
Conclusion: This review will provide an overview of classification, the various formulation methods,
characterization, patented formulations and applications of liposomes with future prospects.
