In the present study, curcumin nanoformulation loaded methoxy poly(ethylene glycol)-graft-chitosan film (curcumin-MPEG-chitosan film) was developed and its applicability in the wound healing was investigated. in vitro cytotoxicity test showed that the developed MPEG-chitosan film was non-cytotoxic. Antioxidant efficiency tests revealed that the antioxidant efficiency of curcumin in the film did not show any significant difference compared with that of unmodified curcumin. Furthermore, in vivo wound healing test showed that the rate of wound reduction was greatly elevated with the rapid re-epithelialization in curcumin-MPEG-chitosan film group. Masson's Trichrome staining and the hydroxyproline measurement in the wound tissue also suggested that application of curcumin-MPEG-chitosan film could greatly increase the collagen synthesis compared with that of MPEG-chitosan film treatment. Therefore, all these results proved the effectiveness of curcumin-MPEG-chitosan film in the application of wound healing. (C) 2011 Elsevier Ltd. All rights reserved.
