Artificially formed single or multi-layer spherical lipid bilayer structures. Made from solutions of lipids etc. in organic solvents dispersed in aqueous media. Under appropriate conditions liposomes form spontaneously. Often used as models of the plasma membrane. May also be used experimentally and therapeutically for delivering drugs etc. to cells since liposomes can fuse with a plasma membrane and deliver their contents to the interior of the cell. Vary in size from submicron diameters to (in a few record-breaking cases) centimetres.
