Asahi Kasei announces the results of joint research with Nara Medical University regarding the efficacy of 226 nm ultraviolet-C (UVC) LEDs in the inactivation of the coronavirus (SARS-CoV-2) that causes COVID-19, and its effects on animal skin cells.
Key Points:
- Asahi Kasei announces the results of joint research with Nara Medical University regarding the efficacy of 226 nm ultraviolet-C (UVC) LEDs in the inactivation of the coronavirus (SARS-CoV-2) that causes COVID-19, and its effects on animal skin cells.
- This is the first study in the world conducted with LEDs of this wavelength, and the results confirm that the 226 nm UVC LEDs are able to quickly inactivate SARS-CoV-2 while having significantly less effect on animal skin cells than 270 nm UVC LEDs.
- An additional experiment was conducted on mouse skin cells to estimate the damage that 226 nm UVC LED light has on animal skin compared with 270 nm light.
- The above results indicate that 226 nm UVC LEDs can quickly inactivate SARS-CoV-2 while having significantly less effect on animal skin cells compared to the current generation of 270 nm UVC LEDs for disinfection.
