Just two days ago, we told you about a new study from South Korea that claimed UV light was used to kill coronavirus in 30 seconds. The study was conducted by a South Korea-based company Viosys and U.S.-based Sensor Electronic Technology, Inc. (“SETi”). The two companies said they successfully killed 99.9% of coronavirus (COVID-19) in 30 seconds using a compound semiconductor Violeds technology that is being mass-produced. Violeds is a patented technology that includes UV LEDs, UV LED fixtures and UV LED systems. The tests were conducted with the research group of Korea University, Korea’s top rank university.
Now, there is a similar study that just came out of Columbia University’s Center for Radiological Research. Their new technology is based on the idea of using UVC light to kill viruses. According to David Brenner, professor of radiation biophysics and director of the center, the Center for Radiological Research has developed a new technique that zaps airborne viruses with a narrow-wavelength band of UV light shows promise for curtailing the person-to-person spread of COVID-19 in indoor public places. Professor Brenner believes the far-UVC light, which is safe for humans, but lethal for viruses, could potentially be a ‘game changer.’
