Liposomes consist of phospholipids bi-layers that enclose an aqueous compartment where drugs can be contained for delivery to specific tissues if target proteins are present.
Liposome used as target selective membrane surface structure can be modified for specific drug targeting for changing the charge on the membrane ,adding specific proteins and antibodies or immunoglobulins. Liposome involves an aqueous core entrapped by one or more bi-layers composed of natural or synthetic lipids.
Passive targeting , liposome penetrate the tumor cell using molecular influx through the cellular membrane. Active targeting liposome target the intended tumor tissue with the help of antibodies capable to identify as specific tumor tissue. That composed of natural phospholipds that are biologically inert and feebly immunologic and low inherent toxicity.
