Air Force Treating Wounds With Lasers and Nanotech
Forget stitches and old-school sutures. The Air Force is funding scientists who are using nano-technology and lasers to seal up wounds at a molecular level.
It might sound like Star Trek tech, but it’s actually the latest in a series of ambitious Pentagon efforts to create faster, more effective methods of treating war-zone injuries.
Last year, the military’s research agency, Darpa, requested proposals for instant injury repair using adult stem cells, and Pentagon scientists are already doing human trials of spray-on skin.
Massachusetts General Hospital researchers Irene Kochevar, Robert Redmond and dermatologist Sandy Tsao are behind the nano-tech project, which has been funded by various agencies within the Department of Defense for eight years. They’ve successfully tried out the nano-sutures in lab experiments and a clinical trial of 31 patients in need of skin incisions.
The process would replace the sutures and staples traditionally used to repair wounded skin. Instead of being sealed up with a needle and thread, a patient’s wound would be coated in a dye, then exposed to green light for 2-3 minutes. The dye absorbs the light and catalyzes molecular bonds between the tissue’s collagen.
The bonds instantly create a seal that’s watertight, which prevents inflammation or risk of infection, and speeds up the formation of scar tissue.
