Abstract
The disclosure relates to multilayered vesicles, methods for forming multilayered vesicles, and drug delivery complexes including multilayered vesicles. The multilayered vesicles can be formed by adding hydrophobe containing polypeptoid (HCP)-lipid complexes to unilamellar vesicles such as liposomes in an amount effective to form multilayered vesicles. The HCP-lipid complexes can be produced by mixing a hydrophobe containing polypeptoid (HCP) with a first set of unilamellar vesicles. The unilamellar vesicles and/or drug delivery complexes can include various cargoes for delivery, such as water-soluble cargoes, hydrophobic cargoes, etc.
