Viral disinfection using nonthermal plasma: A critical review and perspectives on the plasma-catalysis system

Chemosphere. 2022 Dec;309(Pt 1):136655. doi: 10.1016/j.chemosphere.2022.136655. Epub 2022 Sep 30.

Abstract

The transmission of viral infections via aerosol has become a serious threat to public health. This has produced an ever-increasing demand for effective forms of viral inactivation technology/processes. Plasma technology is rising in popularity and gaining interest for viral disinfection use. Due to its highly effectively disinfection and flexible operation, non-thermal plasma (NTP) is a promising technology in decontaminating bacteria or virus from air or surfaces. This review discusses the fundamentals of non-thermal plasma and the disinfection mechanisms of the biocidal agents produced in plasma, including ultraviolet (UV) photons, reactive oxygen species, and reactive nitrogen species. Perspectives on the role of catalysts and its potential applications in cold plasma disinfection are discussed.

Keywords: Inactivation mechanism; Non-thermal plasma; Plasma-catalysis; Viral inactivation.
