Abstract
Polymeric and hybrid aqueous-core nanocapsules were prepared using a low energy organic-solvent free procedure as innovative nanodevices for the ophthalmic delivery of melatonin. In order to evaluate how different cationic lipids could affect the main properties of the nanodevices, we focused our attention on mean particles size, surface charge, shape and stability (the "4S"). The results of our study confirmed the hypothesis that the coating material differently affects the overall nanoparticles properties, above all in terms of morphology: in particular, the cationic lipid dimethyldioctadecylammonium bromide allows the formation of very stable well-defined nanocapsules with non-spherical shape with sustained and prolonged drug release, thus representing a great advantage in ophthalmic application.Entities:
