Osaka, Japan – Panasonic Corporation has verified the inhibitory effect of nanoe™ technology with benefits of hydroxyl radicals on four novel coronavirus variants, namely Alpha, Beta, Gamma, and Delta, in collaboration with the Japan Textile Products Quality and Technology Center (QTEC) *1.
nanoe™ the original ionizer to generate “nano-sized atomized water particles” is developed by Panasonic. It is an electrostatic atomization technology, that collects invisible moisture in the air and applies high voltage to it to produce “hydroxyl radicals contained in water”. The decisive factor is the existence of hydroxyl radicals inside nanoe™. Hydroxyl radicals are characterized by being strongly oxidative and highly reactive.
Panasonic has been conducting research on this technology over the past 20 years since 1997, and has verified its effectiveness in a variety of areas, including inhibiting pathogenic microorganism (bacteria, fungi, and viruses) and allergens, breaking down PM 2.5 components that have adverse effects on the human body *2.
In July 2020, Panasonic verified the inhibitory effect of nanoe™ on novel coronavirus (SARS-CoV-2)*3. Prior to this announcement, in 2012, Panasonic conducted a virus clearance test with a third-party organization and confirmed the effectiveness on each of the 4 categories in terms of biological characteristics. Based on this result, Panasonic announced that nanoe™ technology could be expected to have an inhibitory effect on new viruses*4. In light of these facts, nanoe™ can be expected to have an effect on novel coronavirus variants. The company conducted a verification again in view of the current status of the spread of viral infection.
During the latest verification test, the virus titers of novel coronavirus (SARS-CoV-2) and its four variants (Alpha, Beta, Gamma, and Delta) were compared in a 45-liter test space with and without exposure to nanoe™. As a result, the test confirmed an inhibitory effect of more than 99% on all five types of viruses after two hours of exposure. Note that the verification results are based on the test in a closed test environment and not in a space actually in use.
Panasonic will continue to pursue the potential of the nanoe™ technology and verify its various effects in order to contribute to society.
■ For reference
Testing of inhibitory effect of nanoe™ on four novel coronavirus variants.
A comparative verification was conducted in a 45-liter test space containing the four novel coronavirus variants with and without exposure to nanoe™.
Over 99% of four novel coronavirus variants activity was inhibited within 2 hours.
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. It was not designed to evaluate product performance.
