Cold atmospheric plasma decontamination of SARS-CoV-2 bioaerosols

Bioaerosols (aerosolized particles with biological origin) are strongly suspected to play a significant role in the transmission of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), especially in closed indoor environments. Thus, control technologies capable of effectively inactivating bioaerosols are urgently needed. In this regard, cold atmospheric pressure plasma (CAP) can represent a suitable option, thanks to its ability to produce reactive species, which can exert antimicrobial action. In this study, results; on the total inactivation of SARS-CoV-2 contained in bioaerosols treated using CAP generated in air are reported, demonstrating the possible use of CAP systems for the control of SARS-CoV-2 diffusion through bioaerosols.

Automated summary

This study demonstrates the potential use of cold atmospheric pressure plasma (CAP) for controlling the diffusion of SARS-CoV-2 through bioaerosols by effectively inactivating the virus contained in bioaerosols using CAP generated in air.
