Recent advances in biopolymer-based formulations for wound healing applications

Since decades, the field of wound healing has gained immense attention from the researchers worldwide. The ultimate goal is to develop effective techniques that can speed up the healing process and avoid scar formation to facilitate proper wound management. This has resulted in advances and discoveries in different biopolymeric nanosystems and their combinations as wound healing agents as alternatives for conventional wound dressings. This review primarily outlines wound healing cascade by human body’s natural defence mechanism and highlights the recent developments in wound healing agents. The aim of the review is to discuss the suitability of biopolymeric nanosystems based on chitin, chitosan, collagen, alginate, fucoidan, gelatin, silk fibroin and hyaluronic acid as potential wound healing agents to provide wound healing environment for enhanced healing rate.
