Abstract: Disclosed herein are wound healing products and methods of making and using the same. The wound healing product comprises a porous scaffold and collagen bound thereon. The scaffold may comprise a poly(L-lactide-co-ε-caprolactone) polymer (PLCL) substrate. In some embodiments, the PLCL substrate comprises a mixture of poly(lactic acid) (PLA) and poly(ε-caprolactone) (PLC) and wherein the PLA and PLC are present in a ratio of about 60:40 to about 40:60. In some embodiments, the collagen is collagen I or collagen III. The scaffold may also have a thickness of at least 0.2 mm.
