New spray gel could help take the bite out of frostbite

(American Chemical Society) Mountaineers and winter sports enthusiasts know the dangers of frostbite -- the tissue damage that can occur when extremities, such as the nose, ears, fingers and toes, are exposed to very cold temperatures. However, it can be difficult to get treated quickly in remote, snowbound areas. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a convenient gel that could be sprayed onto frostbite injuries when they occur, helping wounds heal.
