The long circulatory liposome means shows action towards target organ longer period of time. Liposome are the concentric bilayer in which aqueous volume entirely envelope by the lipid bilayer used to transfer enzymes, protein and drugs to targets cancer cell or tissue. These are chemical moieties in which action towards target organ. It was first discovered by 1965 and soon was proposed drug delivery system.
