TEL AVIV (REUTERS) – An Israeli company expects to receive results within the coming week from a Beijing lab that will test whether a tissue it has developed will be able to neutralize 99% of Covid-19, even after have been washed several times.
Sonovia claims that its reusable antiviral masks are coated with nanoparticles of zinc oxide that destroy bacteria, fungi and viruses, which she says can help stop the spread of the coronavirus.
The fabric can be used in textiles for hospitals, protective gear and clothing. But the masks are not certified for use by healthcare professionals in operating and emergency rooms, who only use disposable masks, according to Liat Goldhammer, Sonovia’s chief technology officer.
Tests at the Microspectrum lab (Weipu Jishu) in Shanghai showed that the washable fabric used in his masks neutralized 90.67% of the coronavirus he was exposed to, according to a report released by the lab in June and seen by Reuters.
Further testing is underway at an affiliated lab in Beijing.
“We will have results in the next few days,” Goldhammer told Reuters this week. “We expect the test to show 99% effectiveness.”
Sonovia says it has customers in Germany and the United States and is running a pilot project for an Italian company. It also sells its masks online to retail consumers.
The tests in China follow a test in May on equipment from the Austrian medical laboratory HygCen using the Vaccinia virus, which has properties similar to those of the Sars-Covid family. The company Sonovia hired said the test showed “a good virucidal effect,” according to the lab report.
Reuters has not independently confirmed Sonovia’s results.
