London: Hospital superbugs resistant to antibiotics could be eliminated using light beams.A team from the University of Strathclyde in Glasgow, Britain, has developed a pioneering lighting system that can kill unyielding microbes.The technology decontaminates the air and exposes surfaces by bathing them in a narrow spectrum of visible-light wavelengths, known as HINS-light.It works by exciting molecules within the bacteria, which in turn produces `highly reactive` chemical species that are lethal to it, reports the Daily Mail.Clinical trials at Glasgow Royal Infirmary suggest the HINS-light Environmental Decontamination System could provide significantly greater reductions of bacterial pathogens in hospitals than cleaning and disinfection alone.Other methods of decontamination, including gas sterilants or ultraviolet light can also be hazardous to staff and patients.
