<p>The invention provides wound dressings comprising chemically modified polysaccharides, wherein the polysaccharide has been chemically modified by the introduction of one or more thiol groups. Preferably, the modified polysaccharide is the product of a reaction between chitin/chitosan or a cellulose derivative with Lawesson’s reagent. The modified polysaccharides have antioxidant properties and selectively bind to dissolved iron, making them useful to the treatment of chronic wounds and lipodermatosclerosis.</p> |
