liposomeLipid vesicle Drug delivery A synthetic, uniform bilayer lipid membrane-bound vesicle formed by emulsification of cell membranes in dilute salt solutions, which is used to deliver toxic drugs–eg, amphotericin B, doxorubicin, pentavalent antimony–tagging them with an organ-specific antibody.

liposomean artificially constructed PHOSPHOLIPID VESICLE, which can be used in various biological experiments. Certain drugs may be incorporated into liposomes in order to administer them. In this way the drugs may be protected from degradation and may not exert general toxicity when introduced into the bloodstream.
