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.
Biofilms are groups of tiny living things that cling to surfaces. These surfaces can be non-living, like rocks in a stream, or parts of animals, like skin or gut lining.
