The immediate treatment of wounds is highly important on the battlefield as it can be the difference between life and death. A new method to heal wounds by using light in a quick, convenient and safe way has started testing, with funds by the Air Force Office of Scientific Research. This test was carried out by researchers at Massachusetts General Hospital and finished a pilot test to find out the effectiveness of light bonding compared to the conventional stitching method. In addition, this research included patients who had skin wounds removed and needed stitches. According to this research, it is stated that a pink dye zapped with green light can seal a wound instantly. This process is called photochemical tissue bonding, and it can repair skin wounds or even reconnect nerves and blood vessels without using traditional stitches, staples and glues. This method procedure is applies a unique pink dye to the skin around a wound and scans it with a green light. Moreover, the pink dye called “Rose Bengal” is also used to diagnose eye damage by absorbing the lights and exciting electrons.
