Claim:
1. A polymer-liposome nanocomposite, which is a nano-sized composite of a polymer and liposome and comprises a lipid and an alkyl-grafted poly(amino acid), wherein the alkyl-grafted poly(amino acid) is associated with a lipid bilayer containing the lipid, wherein the alkyl-grafted poly(amino acid) is selected from the group consisting of poly(aspartic acid) and poly(asparagine) units, wherein the alkyl grafted onto the alkyl-grafted poly(amino acid) has an aliphatic chain having at least 8 carbon atoms, and is combined at side chains of the alkyl-grafted poly(amino acid), and wherein the alkyl-grafted poly(amino acid) comprises 2 to 1000 alkyl-grafted amino acid units and 1 to 1000 non-alkyl-grafted amino acid units per mole of the polymer.
