Light Kills Stubborn Bacteria

Light Kills Stubborn Bacteria

A novel technology, which uses high-intensity light to eliminate stubborn bacteria from hospitals, has been developed at the University of Strathclyde, Glasgow, Scotland. The new decontamination technique is significantly more efficient in reducing pathogens than cleaning and disinfecting alone. It “works by using a narrow spectrum of visible-light wavelengths to excite molecules contained within bacteria,” explains microbiologist Professor John Anderson.
