Antibiotics with Light Activated Nanoparticles
December 5, 2017 | Terry Sharrer
Drug resistance in several pathogenic species have raised alarms and stimulated a search for new antibiotics. But researchers at the University of Colorado at Boulder have a different approach. They designed nanoparticles (aka quantum dots) which can release a superoxide that makes existing antibiotics more effective. “While other previous antibiotic treatments have proven too indiscriminate in their attack, the quantum dots have the advantage of being able to work selectively on an intracellular level. Salmonella, for example, can grow and reproduce inside host cells. The dots, however, are small enough to slip inside and help clear the infection from within.” MORE
