Sharp develops Plasmacluster tech that reduces airborne novel coronavirus

Plasmacluster technology significantly inactivates SARS-CoV-2 contained in adherent saliva in an environment with 60% humidity where the physiological protective function is maintained

In world’s first, Sharp Corporation, Japan has developed a device equipped with Plasmacluster Ion technology that shows more than 90% reduction on airborne Novel Corona Virus (SARS-CoV-2) in 30 seconds, while when exposed to adhering Novel Corona Virus (SARS-CoV-2) including its Alpha variant in human saliva, it shows more than 99% reduction in 2 hours. 
 
According to Professor Hironori Yoshiyama, Department of Microbiology, Shimane University Faculty of Medicine,  “To prevent virus infection, it is important to maintain the environment at a relative humidity of about 60% by humidification, thereby preventing the human respiratory tract mucosa from drying out, and maintaining the protective function, and to suppress the infectivity of the virus. However, while an environment with a relative humidity of 60% reduces the number of suspended droplet particles, airborne droplet particles fall and adhere to surfaces.

Therefore, it is also necessary to consider the countermeasures against adhering viruses. In this verification, Plasmacluster technology significantly inactivates SARS-CoV-2 contained in adherent saliva in an environment with 60% humidity where the physiological protective function is maintained. The current result also shows its efficacy to the variant strain, which must be applied to new variants that will appear in the future,” he added.
 

Result: Effect of Plasmacluster ions on the infectious titer of novel coronavirus (SARS-CoV-2) suspended in air shown a decrease of 91.3% within 30 seconds of exposure.
