Osaka, Japan – Panasonic Corporation today announced that the company, in collaboration with the Japan Textile Products Quality Technology Center, has verified the inhibitory effect of nanoe™ on novel coronavirus adhering in a 24 m3 test space. This is the first time that the inhibitory effect on adhered novel coronavirus has been verified in a test space almost as large as a daily living space.
nanoe™ is a technology that collects invisible moisture in the air and applies a high voltage to it to produce “hydroxyl radicals contained in water”. Hydroxyl radicals inhibit the growth of pollutants such as bacteria and viruses. They are characterized by being strongly oxidative and highly reactive, hence a short life span. Contained in tiny water particles, nanoe™ has a long lifespan and can spread over long distances. It has an inhibitory effect on both airborne and adhered substances.
The mutation of the amino acid in the spike protein has caused new variant strains with different infectivity, transmissibility, and antigenicity such as the increased binding capacity to cells and reduced binding to neutralizing antibodies. Consequently, the global spread of the novel coronavirus shows no sign of abating. Research is underway to identify the properties of the current dominant Omicron strain, but the increase in secondary infections in households and other factors suggest that its infectivity has increased compared to conventional strains, and further infection prevention measures are crucial.
Concerning the nanoe™ technology, Panasonic verified their inhibitory effect on the novel coronavirus (SARS-CoV-2)*1 in July 2020 and its inhibitory effect on four novel coronavirus variants*2 in November 2021. However, since the former verifications are the results of experiments in a small 45-liter test space, the effects in large spaces were only speculative.
Therefore, Panasonic carried out a comparative experiment in a 24 m3 test space to compare virus titers with and without exposure to nanoe™. A piece of gauze saturated with the Delta strain of the novel coronavirus was exposed to nanoe™ for 8 hours and the inhibitory effect of more than 99% was confirmed. Note that the verification results are based on a test in a closed test environment and not in space actually in use.
Panasonic will continue to pursue the potential of nanoe™ technology using and providing safe and secure spaces to contribute to society.

Testing the inhibitory effect of of nanoe technology confirmed on the adhered novel coronavirus Delta variant (SARS-CoV-2) in a test space of approximately 24m3
A comparative verification was conducted in a 24m3 test space containing the adhered novel coronavirus Delta variant (SARS-CoV-2)
The reduction in virus infection titer of more than 99% against the adhered novel coronavirus Delta variant (SARS-CoV-2) with the nanoe™technology was also verified in a 24 m3 test space.
Note: This verification was designed to generate basic research data on the effects of nanoe™ on the novel coronavirus in laboratory conditions different from those found in living spaces.
