According to foreign media reports, scientists have successfully tested a welding material containing gold nanorods, which can be used to laser weld patients' surgical wounds, thus replacing traditional needle stitching techniques.
This solder contains gold nanorod particles that form a flexible seal that moves through the body. Scientists at the American Institute of Chemistry have now tested this suture material on the pig's intestines, believing it can replace traditional needle-stitching techniques. They found that this technology produces "liquid-tight and elastic seals" and can shorten the operation time of the operation. In addition, this latest technology can reduce scarring compared to suture stitching.
The technology is called "laser tissue welding (LTW)", and scientists at the American Institute of Chemistry hope to further improve laser tissue welding technology to produce a more robust wound suture. Koshar-Raig and colleagues decided to use a solder called a plasma nanomaterial that contains gold nanorods.
The gold nanorods wrapped in the solder will be more elastic, which means that the solder can move in the body, reducing the possibility of suture cracking. Scientists have found that when this material is laser-welded as a light-activated solder to the pig's intestinal incision, it can form a firmer liquid-sealing strip structure with a certain elasticity that avoids harmful bacterial infections.
“All in all, plasma nanomaterials are a surprise for scientists, and they can be used for laser human tissue repair surgery.†The researchers plan to further investigate the suture of animal intestinal wounds to determine whether to replace traditional needle sutures in certain conditions. wound.
