Viral Inactivation and Biocompatibility Study of Electrically Activated Water Mist

Abstract

In addition to the ongoing global problem of healthcare-acquired infections, the COVID-19 pandemic continues to pose a serious threat to the health of the global population. This unprecedented pandemic situation has reinforced the need for the development of technologies that can curb the transmission of viruses among human beings and help to control the infection. Existing disinfection techniques using either ultraviolet light or harsh chemicals pose safety risks and are not suitable for use in the presence of humans. Thus, the need for a safe and effective disinfection technique that can be used in the presence of humans to control viral transmission is evident. A technique that can continuously disinfect air and surfaces in indoor environments, where the chances of viral transmission are high, can be an indispensable tool to fight such a pandemic. The Airlens Minus Corona (AMC) device provided by Persapien Innovations has been developed to achieve this goal. In this study, the antiviral functionality and biocompatibility of AMC were evaluated. Activated water mist (AWM) generated from this device was tested in vitro and in vivo for its toxicity to cell lines and in animal model. The AWM was found to be non-cytotoxic to L-929 cell lines and had no sign of clinical toxicity in an animal model (rabbit). This device was further used to inactivate animal viruses and bacteriophages. The AWM was found to be effective in the complete inactivation of influenza A H1N1 virus within 5 minutes of direct treatment. This device was also found to be effective in inactivating >90% of bacteriophage particles.
