Can a New UV Light Zap the Coronavirus?


A narrow wavelength of ultraviolet (UV) light in public spaces may slow the spread of COVID-19. Scientists at Columbia’s Center for Radiological Research built lamps that shine a light, known as far-UVC, which can kill viruses.

“Far-UVC light has the potential to be a ‘game changer,’” said David Brenner, professor of biophysics and director of the center. “It can be safely used in occupied public spaces, and it kills pathogens in the air before we can breathe them in.”

At indoor locations with many people, like schools or airports, shining far-UVC lights inside may allow us to responsibly recover from COVID-19. Learn more.
