Abstract

Abstract: Nanofi bers (NFs) have been widely used in tissue engineering such as wound healing. In this work, the antibacterial ZnO quantum dots (ZnO QDs) have been incorporated into the biocompatible poly (ε-caprolactone)/collagen (PCL/Col) fi brous scaff olds for wound healing. The as-fabricated PCL-Col/ZnO fi brous scaff olds exhibited good swelling, antibacterial activity, and biodegradation behaviors, which were benefi cial for the applications as a wound dressing. Moreover, the PCL-Col/ZnO fi brous scaff olds showed excellent cytocompatibility for promoting cell proliferation. The resultant PCL-Col/ZnO fi brous scaff olds containing vascular endothelial growth factor (VEGF) also exhibited promoted wound-healing eff ect through promoting expression of transforming growth factor-β (TGF-β) and the vascular factor (CD31) in tissues in the early stages of wound healing. This new electrospun fi brous scaff olds with wound-healing promotion and antibacterial property should be convenient for treating wound healing.
