PVA-based hydrogels for chronic wound healing: a systematic review of mechanical, structural, chemical, and biological performance
Polyvinyl alcohol (PVA)-based hydrogels are promising chronic wound dressings owing to their tunable structure, biocompatibility, and capacity to carry bioactive agents. Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guideline, this review synthesised evidence on their mechan...
