This study aimed to compare the in vivo effectiveness between curcumin-oligochitosan nanoplexes (CUR-OCH nanoplexes) and oligochitosan-coated curcumin-encapsulated liposomes (OCH-Lip-CUR) with respect to wound healing and scar treatment. Firstly, CUR-OCH nanoplexes was prepared by drug-polysaccharide complexation method and OCH-Lip-CUR was prepared by a combining method of lipid-film hydration and sonication. Their in vitro cytotoxicity and in vivo wound healing and scar treatment effectiveness were evaluated using 3T3 cells and mice Mus musculus var. Albino, respectively. The resutls indicated that both of them were in nanosize with a moderate PDI (less than 0.3), and exhibited negligible cytotoxicity at low CUR concentration (0.01 mg/mL). Moreover, their application onto wounds resulted in faster healing and higher scar treatment effectiveness than control samples. Interestingly, OCH-Lip-CUR exhibited higher in vivo effectiveness than CUR-OCH nanoplexes. However, based on their own advantages, both of them were good candidates for a commercial formulation for wound healing and scar treatment.
