Nanosuturing: Using light to stitch a wound

I am reminded of a scene from the science fiction movie Logan’s Run where a plastic surgeon uses a laser to cut the skin, makes the cosmetic change, and then seals the wound with a laser leaving no scar. Although this seemed an impossible feat of technology at the time, real science has edged closer to it.

Researchers at the Massachusetts General Hospital are using light to “stitch” surface wound openings back together. The process is called nanosuturing or photochemical tissue bonding.
