New light-activated nanoparticles kill over 90% of antibiotic-resistant bacteria

A new nanoparticle treatment developed by researchers at the University of Colorado Boulder could solve the growing problem of antibiotic-resistant bacteria including Salmonella, E. Coli, and Staphylococcus. In testing with a lab-grown culture, the nanoparticles killed 92 percent of drug-resistant bacterial cells while leaving the other cells intact.
The treatment consists of light-activated therapeutic nanoparticles called "'quantum dots". These extremely small particles, which resemble the semiconductors used in electronics, are about 20,000 times smaller than a human hair, and when excited by light they prove deadly to drug-resistant bacterial cells.
