Quantitative evaluation of SARS‑CoV‑2 inactivation using a deep ultraviolet light‑emitting diode

See — Inactivation technology for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is certainlya critical measure to mitigate the spread of coronavirus disease 2019 (COVID-19). A deep ultravioletlight-emitting diode (DUV-LED) would be a promising candidate to inactivate SARS-CoV-2, based onthe well-known antiviral efects of DUV on microorganisms and viruses. However, due to variationsin the inactivation efects across diferent viruses, quantitative evaluations of the inactivation profleof SARS-CoV-2 by DUV-LED irradiation need to be performed. In the present study, we quantify theirradiation dose of DUV-LED necessary to inactivate SARS-CoV-2. For this purpose, we determinedthe culture media suitable for the irradiation…
