In this study, poly (ɛ-caprolactone)–chitosan–poly (vinyl alcohol) nanofibrous scaffolds used on canine skin wound models were found to significantly accelerate healing rates of excision and burn wounds, without inducing immunogenic reactions.

This study developed a bilayer material combining poly(vinyl alcohol) and bacterial cellulose with a gelatin-poly(vinyl alcohol) hydrogel, showing strong potential as a wound dressing due to its good antibacterial properties, cell viability, and sustained drug release.

This study reported that nanofibrous scaffolds made from a PVA and flaxseed extract combination showed enhanced antimicrobial activity and significantly better wound healing in vitro compared to pure PVA fibers.

Human hair keratin was used to create a scaffold that could help with skin repair.

This review outlines strategies for regulating macrophage response using bioactive materials to enhance wound healing, focusing on extracellular matrix-based scaffolds and nanofibrous composites, but reports no new clinical results.
