Liposome Drug Delivery: A Promising Nanocarrier System for Targeted Therapeutics

Liposomes are spherical vesicles consisting of lipid bilayers that can encapsulate both hydrophilic and hydrophobic compounds. Originally developed in the 1960s as model cell membranes, liposomes found new applications as drug carriers in the 1970s. Since then, liposomal formulations have revolutionized drug delivery.
