Sharp helps combat Coronavirus with world-first Plasmacluster technology

New technology from Sharp is the first in its area to be verified in combatting Coronavirus.

The Japanese manufacturer is one of the first companies in the world to develop a device in which the airborne Coronavirus was exposed to Plasmacluster ions. A new laboratory study has confirmed the efficacy of Plasmacluster ion technology on the virus.

After about 30 seconds, a reduction of infectious airborne virus particles by approximately 90 per cent was observed in the study, which was conducted in collaboration with the National Research Center for Infectious Disease Control and Prevention, the Institute of Tropical Medicine of Nagasaki University, experts from the Microbiology Department of Shimane University, and members of the Japanese Society for Virology. The University of Nagasaki is an internationally respected authority in the field of infectious disease research.

“The pandemic poses a great challenge to society and calls for immediate help in many areas,” the company said. The COVID-19 pandemic, caused by the novel coronavirus (SARS-CoV-2), officially appeared for the first time in December 2019; by October 2020, more than 37 million people worldwide were infected with the virus and around one million died.

Back in 2004, Sharp proved the effectiveness of its patented Plasmacluster ion technology, used in Sharp air purifiers – similar to the one pictured left – against the ‘Feline Coronavirus’, which also belongs to the Coronaviridae family. The following year, the manufacturer also demonstrated the technology’s effectiveness against the primary SARS Coronavirus that caused the 2002-2003 outbreak and is genetically similar to the novel Coronavirus now present.

Since 2000, Sharp has been cooperating with independent research organisations around the world to demonstrate the effectiveness of Plasmacluster technology. At the same time, the safety of Plasmacluster ions has also been confirmed.

The company said it will continue to conduct further studies to demonstrate the efficacy of this technology, which it said makes an important contribution to society.

Commented Dr. Jiro Yasuda, Professor, National Research Center for the Control and Prevention of Infectious Diseases, Nagasaki University: “Disinfectants such as alcohol and detergents 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 homes, offices, medical facilities and vehicles.”
