A series of polydiacetylene (PDA) - based micelles were prepared from diacetylenic surfactant bearing polyethylene glycol, by increasing UV-irradiation times. These polymeric lipid micelles were analyzed by physicochemical methods, electron microscopy and NMR analysis. Cellular delivery of fluorescent dye suggests that adjusting the polymerization state is vital to reach the full in vitro potential of PDA-based delivery systems. Photopolymerized micelles of diacetylenic amphiphiles bearing polyethylene glycol headgroups allow for enhanced intracellular delivery of hydrophobic dye molecules.
