Plasmacluster Technology Demonstrates Effectiveness in Reducing Airborne Novel Coronavirus (SARS-CoV-2)*1, a World First*2
In a world-first, Sharp Corporation developed a device equipped with Plasmacluster technology, which exposed an airborne novel coronavirus (SARS-CoV-2) to Plasmacluster ions for approximately 30 seconds*3, and demonstrated that the virus infectious titer*4 was reduced more than 90%. This achievement was accomplished in collaboration with Professor Jiro Yasuda of the National Research Center for the Control and Prevention of Infectious Diseases/Institute of Tropical Medicine, Nagasaki University, Professor Asuka Nanbo (a Board member of the Japanese Society for Virology) of the same institution, and Professor Hironori Yoshiyama of the Department of Microbiology, Shimane University Faculty of Medicine (also a Board member of the Japanese Society for Virology), and in cooperation with Nagasaki University, an internationally respected authority on infectious disease research.
Comments from Dr. Jiro Yasuda, Professor, National Research Center for the Control and Prevention of Infectious Diseases, Nagasaki University
Disinfectants such as alcohol and detergents (surfactants) are well-known to be effective to reduce the risk of the virus on materials, however, for infection via aerosols (microdroplets), there are few effective countermeasures such as a mask.
Here, effective inactivation of SARS-CoV-2 in airborne droplets by Plasmacluster technology was demonstrated.- It would be expected that it is useful to reduce the risk of infection in real spaces including office, home, medical facilities and vehicles.
