Liposomes consist of bilayers that enclose an aqueous compartment where drugs can be contained for delivery to specific tissues if target proteins are present.

Phospholipid bilayer

Explanation:

Liposomes are vesicles are spherical in shape. They consist of at least one phospholipd bilayer most especially phosphatidycholine. Liposomes are artficial vesicles similar to a membrane, because it has an hydrophilic core surrounded by a hydrophobic lipid bilayer.

Liposomes are artificial prepared and are used for the transportation of substances like drugs and nutrients between cell parts, outside of the cell and into the cell.  

In liposomal drug delivery, the liposome fuses with other internal cell membranes at the site of action and releases its liposomal content.
