Using lasers to heal cuts

From MIT Tech Review:

“Many believe that lasers should be used not just to create wounds but to mend them too. Abraham Katzir, a physicist at Tel Aviv University, has a system that may just do the trick and is proving successful in its first human trials.

In principle, “laser-bonded” healing offers certain advantages over classic needle-and-thread sutures, including faster healing, decreased risk of infection, and less scarring. Researchers have been working toward flesh-welding lasers for more than a decade, and a number of human trials have shown promise. But what was lacking, until now, was consistency.”
