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 the technology using "hydroxyl radicals contained in water" on novel coronavirus adhering in a 24 m3 test space . This is the first time in the world that the inhibitory effect on adhering novel coronavirus has been verified in a test space almost as large as a daily living space.
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.
With regard to the technology using "hydroxyl radicals contained in water," Panasonic verified their inhibitory effect on the novel coronavirus (SARS-CoV-2)*2 in July 2020 and its inhibitory effect on four novel coronavirus variants*3 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 "hydroxyl radicals contained in water." A piece of gauze saturated with the Delta strain of the novel coronavirus was exposed to "hydroxyl radicals contained in water" for 8 hours and it was confirmed an inhibitory effect of more than 99%. Note that the verification results are based on a test in a closed test environment and not in a space actually in use.
Panasonic will continue to pursue the potential of the technology using "hydroxyl radicals contained in water" and provide safe and secure spaces in order to contribute to society.
