Welding wound

It seems that the stitches are about to run out, after the surgeon has successfully applied the technique of "welding" new wounds, using lasers and . gold.

Accordingly, welds containing gold molecules can form a stretchy patch that moves with body movement. Scientists from the American Chemical Society have tested the gold weld on pig intestines before drawing a conclusion that it can replace traditional stitches, according to phys.org, the results show speed. surgery is faster than traditional patching, and scarring is less than normal.

This method is called laser tissue welding (LTW) . US experts have used gold nanoparticles contained inside a material to make it more elastic, reducing the risk of wound puncture or thread breakage. When applying pig surgery, they found new materials, activated by light, that formed a tough, tight and durable patch.

Once the wound is patched, the harmful bacteria inside will not leak out. Researchers plan to experiment with new materials in animals, before deciding to replace the method of wound healing (such as intestines) for a long time with a new approach, in some cases.
