COVID Tech Spotlight: Potential UV-Light Breakthrough

When airborne droplets laden with COVID-19 were exposed to a specific wavelength of ultraviolet light, more than 99.9 percent of the viral particles were killed, according to new research at the Columbia University Irving Medical Center. The researchers, led by scientist David Brenner, recently published a paper discussing the effect potentially human-safe far-UVC rays have on the coronavirus family. “Based on our results,” writes Brenner, “continuous airborne disinfection with far-UVC light at the current regulatory limit could greatly reduce the level of airborne virus in indoor environments occupied by people.”
