Abstract
Bacterial infection and severe wound inflammation are two primary harmful problems that bring harm to the human body and may cause death when a large-scale skin defect occurs. Thus, developing an effective and quick wound healing strategy for curing skin damage and trauma is vital. This study has developed a multifunctional PLA/gelatin/ZnO nanofiber aerogel with a three-dimensional structure through electrospinning and freeze-drying technology for wound healing. It has validated that the nanofiber aerogel has an excellent antibacterial property and biocompatibility. Meanwhile, benefiting from its three-dimensional nanofiber structure, the PLA/gelatin/ZnO nanofiber aerogel possesses good water absorption and air permeability. In vivo experiments have determined that the PLA/gel/ZnO nanofiber aerogel scaffolds effectively promote skin infection’s wound healing and enhance angiogenesis that is practical with increasing ZnO concentration.
