Has NanoFlashing been tested against SARS-CoV-2, the COVID-19 virus?

In a laboratory test, live SARS-CoV-2, the virus that causes COVID-19, was reduced on contact with treated material; that test did not pass the virus through a filter in moving air.

Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences, report dated 29 April 2021, tested a treated material under ISO 18184. The virus in that test was live SARS-CoV-2; it is a contact test on the material against an untreated control, not an airborne result. The Viruses page shows airborne virus at 1.3 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the virus, and destroys it.” The Mold page shows airborne mold spores at 1.6 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the mold, and destroys it.” The Mold page also states that researchers at Massachusetts General Hospital and Harvard Medical School, in a study with funding from the U.S. National Institutes of Health, tested NanoFlashing™ with more than 100 million live, dry spores driven in by fast-moving air. The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge. The peer-reviewed paper is Gong, Or, Sze et al., Microbiology Spectrum 12(9), e0409723, American Society for Microbiology, September 2024, doi 10.1128/spectrum.04097-23. The paper reports laboratory results on SARS-CoV-2 in contact with treated textile, on aerosolised bovine coronavirus passed through a test filter in a wind tunnel, and on bacterial viability on treated textiles; each result belongs to the article that was tested. A second peer-reviewed paper, Scientific Reports (2023) 13:13947, compared a C-POLAR treated filter with an untreated spunlace nonwoven filter against an aerosolised pseudotyped virus, and reports that the treated filter captured more of it. That virus is the pseudo-type SARS-CoV-2 named on the Validation page, a laboratory model, not live SARS-CoV-2. Tampere University, Department of Virology, report dated 1 April 2021, tested a treated material against human coronavirus 229E and Coxsackievirus B6. Neither of those two viruses is SARS-CoV-2. Each of these is a laboratory result; none is a result on a filter in use in a building, and none measures COVID-19 in people.
