Rational design and latest advances of polysaccharide-based hydrogels for wound healing

Abstract

Acute and chronic wounds cause severe physical trauma to patients and also bring an immense socio-economic burden. Hydrogels are considered to be effective wound dressings. Polysaccharide possessing distinctive properties such as biocompatibility, biodegradability, and nontoxicity, is a promising candidate to structure hydrogels for wound healing. Polysaccharide-based hydrogels can provide suitable moisture of the wound and act as a shield against bacteria. Adequate mechanical properties, degradability, and therapeutic agents controlled release of polysaccharide-based hydrogels have been already characterized for effective utilization. This review presented several crucial design considerations about hydrogels for wound healing, and the current state of polysaccharide (chitosan, alginate, hyaluronic acid, cellulose, dextran, and starch)- based hydrogels as wound dressings was also summarized. The commonly used crosslinking techniques, including physical, chemical, and enzymatic crosslinking, are discussed in detail. Finally, we outline the challenges and perspectives about the improvement of polysaccharide-based hydrogels.
