Also this is a little bit exciting... let's hope that 405nm blue light is also effective. Could be huge! The main issue with UV light is that it's not safe for humans, and has to be administered carefully.
https://www.livescience.com/uv-light-kill-coronavirus.html"UVC has been used for years, it's not new," Indermeet Kohli, a physicist who studies photomedicine in dermatology at Henry Ford Hospital in Detroit, told Live Science. UVC at a specific wavelength, 254 nanometers, has been successfully used to inactivate H1N1 influenza and othercoronaviruses, such as severe acute respiratory virus (SARS-CoV) and Middle Eastern Respiratory Syndrome (MERS-CoV), she said. A study published June 26 to the preprint databasemedRxivfrom Kohli's colleagues awaiting peer review now confirms that UVC also eliminates SARS-CoV-2.
UVC-254 works because this wavelength causes lesions in DNA and RNA. Enough exposure to UVC-254 damages theDNAand RNA so that they can't replicate, effectively killing or inactivating a microorganism or virus.
"The data that backs up this technology, the ease of use, and the non-contact nature" of UVC make it a valuable tool amid the pandemic, Kohli said. But responsible, accurate use is critical. UVC's DNA-damaging capabilities make it extremely dangerous to human skin and eyes, Kohli said. She cautioned that UVC disinfection technologies should primarily be left to medical facilities and evaluated for safety and efficacy by teams with expertise in photomedicine and photobiology.
