What if you could wield a laser sword against microscopic invaders, not in a galaxy far, far away, but in your own body?
Scientists have developed a technique using laser-heated gold nanoparticles to visualize and destroy bacterial biofilms. This approach, tested on rodent teeth and skin wounds, may someday potentially replace antibiotics and treat drug-resistant superbugs.
New Therapy Fights Bacteria Without Antibiotics
Researchers at the University of Pennsylvania and Stanford University have developed a novel technique using sugar-coated gold nanoparticles. When heated by near-infrared lasers, these nanoparticles can both show and destroy biofilms in infected teeth and skin wounds of rats and mice.
