For one, it's obviously much harder to reach that surface to put a dressing on it, but even when its open, say during surgery, the slippery mucus lining prevents bandages sticking. Now, researchers from Harvard have developed spray-on hydrogels, produced by bacteria, that can help heal these internal wounds.
