Delivery of Biomolecules Using Chitosan Wound Dressings

The role of wound dressings has significantly transformed from by providing a simple protective function to dressings that actively participate in every stage of the wound healing process. Chitosan is one of the most widely exploited materials for the synthesis of many functional wound dressings that actively participate at every wound healing stage from facilitating blood clotting to remodelling. In addition to its natural wound healing properties, chitosan is also a versatile polymer that is compatible with many drugs. This has witnessed the increase in the application of chitosan wound dressings for the delivery of a wide variety of structurally different biomolecules that promote wound healing. This chapter reviews the different biomolecules that have been incorporated into different forms of designed chitosan wound dressing materials.
