Description
Summary:Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019 and spread globally to cause severe damage to public health and economics worldwide as coronavirus disease 2019 (COVID-19). A deep ultraviolet light-emitting diode (DUV-LED) would be a promising candidate for the inactivation technology of SARS-CoV-2 to mitigate the spread of COVID-19. The DUV-LED has the potential to provide energy-efficient and contact-less virus inactivation technology with no residual substances after treatment, little effect on targets and the applicability of various viruses, including virus variants. This paper introduces an overview of the virus inactivation technology using DUV-LED and discusses the effect of the DUV-LED irradiation on the SARS-CoV-2.
