Sharp’s Plasmacluster™ Technology Capable Of Reducing More Than 90% Of SARS CoV 2 Virus Within 30s

The world is still battling the global pandemic Covid-19. It has created massive impacts to our world economy and our daily living in year 2020, taking a toll on us human beings and our world economy. As the whole world is currently working towards a vaccine for Covid-19, we are also changing how we live and work, understanding more about personal hygiene and standards for our home, public spaces and workplaces. Sharp Corporation developed a device, a world’s first, equipped with Sharp’s Plasmacluster™ Technology Capable Of Reducing More Than 90% Of SARS CoV 2 Virus Within 30 seconds.

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.

In December 2019, an outbreak of “Coronavirus disease 2019 (COVID 19)” caused by a novel coronavirus (SARS CoV 2) was reported, and by August 2020, more than 25 million people have been infected with SARS CoV 2 and more than 840,000 individuals died of this infectious disease in a world. This outbreak represents an urgent problem facing society, and demands that immediate countermeasures be taken across a wide range of fields.

In 2004, Sharp demonstrated the effectiveness of Plasmacluster™ technology against feline (cat) coronavirus, a member of the Coronaviridae family. In the following year, 2005, Sharp also demonstrated its effectiveness against the original SARS coronavirus (SARS CoV), which caused the outbreak (2002-2003) and genetically similar to the novel coronavirus (SARS CoV 2). Now, Sharp has demonstrated its effectiveness against SARS CoV 2 in airborne droplets. Since 2000, Sharp has promoted academic marketing to demonstrate the effectiveness of Plasmacluster™ Technology, working in collaboration with independent third-party research organizations around the world. Thus far, numerous independent research organizations have proven its clinical efficacy in suppressing the activity of harmful substances including new pandemic influenza viruses, drug resistant bacteria, and mite allergens, as well as in reducing bronchial inflammation levels in children with asthma. At the same time, the safety of Plasmacluster™ ions has also been confirmed. Sharp will continue to contribute to society by conducting a wide range of studies demonstrating the effectiveness of Plasmacluster™ Technology.

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.

About Plasmacluster™ Technology

Positively charged ions (H+ (H2O)m) and negatively charged ions (O2– (H2O)n) are released into the air simultaneously, and the positive and negative ions instantaneously bond on the surface of airborne bacteria, fungi, viruses, allergens, and the like, becoming OH (hydroxyl) radicals which have very high oxidizing power. This is a unique air purification technology that works to suppress the activity of bacteria, etc., by breaking down proteins on their surface by a chemical reaction.

In a post Covid-19 world, how we work and live are going to change, we are looking new age workplace or hybrid working environments. Our homes, workplace and public places would have emphasis, awareness and implementation of good personal and general hygiene. With Sharp’s Plasmacluster™ Technology, this could be one of the health and hygiene tools that you can put in place in your home and in your office.

Do share this great and important information and knowledge with your loved ones, family, relatives and friends. During this global pandemic Covid-19 situation, we need to help out and look out for each other as much as possible, as well as sharing personal hygiene and health awareness information and news.
