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 in-flammatory 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.
