 This study developed a novel 3D chitosan polyvinyl alcohol-tannic acid porous nanofibre sponge, 3DTA, which has been found to be highly effective at promoting wound healing. The 3DTA sponge has demonstrated excellent hemostatic properties, antibacterial and antioxidant capabilities, and biocompatibility with L929 cells. It also has the potential to be used as a wound dressing for clinical applications. This article was authored by Saham Huang, Dorm Hurry Wang, Stefan Molason-Derskof, and others.
