dc.description.abstract | We describe a promising non-invasive transdermal delivery system comprising block copolymer composite micelles that contained a phase-change material (PCM), photothermal Au nanoparticles (AuNPs), and hydrophobic drugs in the core. To minimize cell toxicity, we developed block copolymer micelles with a poly(epsilon-caprolactone) (PCL) biodegradable core and a hyperbranched polyglycol (hbPG) shell. The hbPG block formed micelles at a low-molecular-weight fraction of a low-molecular-weight block copolymer. The composite micelles showed excellent biocompatibility with cell viability at high concentrations. Visible light irradiation (lambda = 520 nm) of the composite micelles induced the photothermal effects of the AuNPs and melting of the PCM (lauric acid); hence, the drugs were released along with the PCM liquid. The release rate was controlled by the light intensity. Based on in vitro and in vivo skin penetration studies, the skin permeability of the drug remarkably improved under mild light irradiation (18 J/cm(2)) that was much lower than the dose that causes skin damage.
