AI Article Synopsis
- SARS-CoV-2 caused a global pandemic, and ultraviolet (UV) light is recognized as an effective way to inactivate it.
- This study compared the effectiveness of different UV wavelengths (222, 254, 265, and 308 nm) on SARS-CoV-2, finding that wavelengths like 222 nm were efficient, while 308 nm was not effective.
- The findings highlight the significance of UV wavelength selection for applications aimed at inactivating SARS-CoV-2.
Article Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a worldwide pandemic. Ultraviolet (UV) is regarded as a very powerful tool against SARS-CoV-2. However, the inactivating effects of different UV wavelengths on SARS-CoV-2 under the same conditions have hardly been compared. Here, we showed that SARS-CoV-2 cultured in Dulbecco's modified Eagle's medium and 2% fetal bovine serum was efficiently inactivated by irradiation with 222, 254, and 265 wavelengths UV, but not at 308 nm. In addition, it was revealed that UV absorption by DMEM-2% FBS is very efficient at 222 nm. Our results present potentially important information for selecting the optimum UV wavelength according to the application.
