Carbon-polymer dressing for the treatment of chronic ulcers

Abstract

Cryogels are sponge-like, highly porous, interconnected hydrogels formed using a freezing process.They have a large surface area for wound contact and, in this case, with a selective barrier (agarose) that allows the passage of volatile malodorous molecules but not serum proteins. This way agarose scaffold absorbs wound exudate and incorporated activated carbon prevents odorous molecules from escaping. In this study, agarose cryogels, hydrogels and films and their composites with activated carbon (AC) were studied as potential wound dressing materials.
