Natural polymers used in the dressing materials for wound healing: Past, present and future

Abstract Wound healing is a complicated system that necessitates an appropriate environment to aid healing. dressing among the most important external variables in wound repair. Technology advancements have led creation of variety dressings treat various types by focusing on four stages Simplicity application, sterility, antibacterial, non‐adherent, gaseous exchange, non‐toxicity, and other qualities are necessary for dressings. In order fully regenerate restore structure functionality skin, ideal should address demands wound. So, kind used based type injury. This review focuses different natural polymers such as κ‐carrageenan, chitosan, cellulose, gelatin, collagen, alginate, hyaluronic acid, silk fibroin development materials hydrogels, nanofibers, sponges, films, scaffolds owing their features, example, biocompatibility, biodegradability, similarity human extracellular matrix (ECM) which aids process. The commercially available products these also discussed review. However, majority polymer‐based still exhibit number problems like adherence, opaque, fast degradability, lack multifunctionality, thus need be addressed. A naturally inspired smart hour individual monitoring multiple pH, temperature, electrical potentials eases incorporated drug biological molecules per progress with delivery systems.
