Abstract
Provided herein is a small molecule delivery system with illumination-induced small molecule release based on the binary combination of charged liposomes containing small molecules and oppositely charged conjugates of a peptide with a photosensitizer attached to one end of peptide chain, providing binding to liposomes and their permeabilization upon light illumination.
