Lasers are common weapons in science fiction movies, but soon a laser may be used to heal wounds in real life, if scientists at Tel Aviv University are successful with current tests.
As reported on the Reuters website, scientists developed an optical fiber capable of transmitting infrared light and at the same time measuring the heat of the tissue it’s pointed at. This allows them to control the laser’s power accurately and use it to “weld” tissue effectively without any burning or scarring. Collagen aids the bonding process, growing firm as the skin cools down. This laser-aided process may result in stronger bonding with fewer scars than traditional sutures. Initial tests on humans have shown successful healing with less scar tissue
