Accelerated Epidermal Regeneration and Improved Dermal Reconstruction Achieved by Polyethersulfone Nanofibers

Abstract

The characterization of nanofibers showed that the PES membrane has nanoscale, porous, high surface area structure. These properties conferred higher exudate absorption capacity for the PES scaffold which is essential for effective wound healing. In vitro results indicated that the PES scaffold can support fibroblast proliferation similar to that with tissue culture polystyrene. Epithelial regeneration was expeditiously accelerated under PES as compared with Vaseline gauze. Greater fibroblast maturation, improved collagen deposition and faster edema resolution were the superior properties of PES over the commercial dressing. Based on these results we conclude that the biocompatible PES nanofibers can effectively be used as a dressing to accelerate wound healing.
