as a my undergraduates research, i have an idea about develop anti bacterial coating using chitosan and aloe Vera gel. So, after develop coating it should be apply on external surface of surgical tape. The main reason is reduce the bacterial contamination around the wound sometimes because of bacterial infections wound can be increased and difficult to cure. Also i think apply biodegradable adhesive agent to composite bind on external surface of surgical tape. Can i know what are the can be used biodegradable adhesive agent and any suggestions for my research topic....?
