Microbe-killing short-wavelength UV radiation produced by LEDs

An array of low-voltage LEDs that emit short wavelength ultraviolet (UV) light could be used to kill harmful microbes on the skin and in the throat and nose – with minimal harmful side-effects to patients. The prototype device was developed by researchers at Germany’s Ferdinand Braun Institute and the Technical University of Berlin, who are currently testing its safety and efficacy.
