Abstract
Use of a moulding composition comprising a polymer and a setting agent for wound debridement, wherein said use comprises adding water to said moulding composition to form a moulding fluid, applying said moulding fluid to a surface of a wound, allowing said moulding fluid to set in contact with said surface to form a solid covering on said surface, followed by removing said solid covering from the wound. The alginate composition adheres strongly to bacterial biofilms on the wound, whereby the biofilms are removed with the alginate composition. The moulding composition may be used in conjunction with a staining agent that undergoes a color change in the presence of bacteria or bacterial polysaccharides to show the presence and removal of the biofilm. Also provided are methods of treating wounds using the compositions.
