<p>Indian scientists have found a new material with surprising self-healing properties that can be exploited to tailor a quick wound healing patch for soldiers in conflict zones or victims of a bomb blast.<br /><br /></p>.<p>If the researchers can finally make a medical product out of this wonder material known as self-healing hydrogel, it would be of immense benefit to soldiers in a conflict zone or the victims of any disaster, many of whom require temporary on the spot healing of wounds before they are transported to a hospital for surgery.<br /><br />The quick wound healing would prevent blood loss and hence save lives.
