Mechanisms underlying inactivation of SARS-CoV-2 by nano-sized electrostatic atomized water particles.

ABSTRACT: The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a serious global issue. To prevent viral transmission, it is important to disinfect contaminated environmental surfaces and aerosols. We previously demonstrated that nano-sized electrostatic atomized water particles (NEAWPs) inactivate SARS-CoV-2. Herein, we focused on the underlying mechanisms. Morphological observation by transmission electron microscopy revealed that compared with NEAWPs-untreated virus, the shapes of particles corresponding to the size of SARS-CoV-2 particles were distorted significantly when exposed to NEAWPs. The amounts of viral RNA and protein in NEAWPs-treated SARS-CoV-2 showed a significantly greater decline than those in viruses unexposed to
