VermaAbstractSquamous cell carcinoma treatment has limited therapeutic options and the incidence rate is increasing recently. In the present investigation, we developed poly(lactic-co-glycolic acid) (PLGA) nanopatterned films (NPFs) through poly dimethyl siloxane (PDMS) cast molding technique and explored its therapeutic efficacy in combination with curcumin and tocopherol poly (ethylene glycol) 1000 succinate (TPGS). Herein, we demonstrate the preparation and characterization of curcumin loaded tocopherol polyethylene glycol 1000 succinate stabilized poly (lactic-co-glycolic) acid nanopatterned films (CTP-NPFs). CTP-NPFs showed good in vitro cytotoxicity towards human skin cancer cell line (A431) when compared to that of unpattern films. CTP-NPFs effectively reduced the progression of cancer cells in vivo, in the skin carcinogenesis model in Swiss albino mice induced by 7, 12-Dimethylbenz[a]anthracene (DMBA)/croton oil. The nanopatterned films could be used as an alternate treatment for skin cancer.Graphical abstract
