The recent research progress of polyphenol-derived biomaterials in wound repair

The clinical requirements for wound care are increasing daily, and the global wound dressing market is expanding; however, the research and development of new wound dressings are imminent. Natural biomolecules such as polyphenols, have been widely used in this field of vision. Owing to their unique anti-oxidative, adhesive, antibacterial and other bioactive functions, researchers have developed a series of wound dressings with excellent performance and applied them to a variety of biomaterials, such as hydrogels, nanofibers, films and scaffolds. They can effectively promote angiogenesis and fibroblast migration and proliferation, scavenge active oxygen free radicals, inhibit excessive inflammatory reactions at wound sites and ultimately accelerate wound healing. The authors summarise the latest progress in polyphenol-derived biomaterials in skin wound repair to provide inspiration for future wound dressing research.
