Chitosan, a biopolymer derived from chitin, has emerged as a promising biomaterial in wound healing due to its biocompatibility, biodegradability, and antimicrobial properties. This review discusses the role of chitosan-based biomaterials in wound healing, their mechanisms of action, and their potential applications in various medical fields. Chitosan's ability to promote cell migration, reduce inflammation, and maintain a moist wound environment makes it effective for accelerating wound healing. It is also used in tissue engineering, drug delivery, and as a component in medical implants and biosensors. Chitosan-based materials, such as hydrogels, membranes, and scaffolds, have shown potential in treating chronic wounds, burns, and diabetic ulcers. These materials offer advantages over traditional dressings, including reduced need for mechanical debridement and improved healing outcomes. Chitosan's antimicrobial properties make it useful in preventing infections, while its biodegradability and biocompatibility ensure safe use in various medical applications. The review highlights the versatility of chitosan in different forms, including nanofibers, hydrogels, and membranes, and its potential in future medical treatments. Chitosan is also being explored for its applications in dentistry, drug delivery, and tissue engineering. Overall, chitosan-based biomaterials are a valuable resource in the field of medicine due to their unique properties and wide range of applications.Chitosan, a biopolymer derived from chitin, has emerged as a promising biomaterial in wound healing due to its biocompatibility, biodegradability, and antimicrobial properties.
