A partnership between several Portuguese companies and scientific and academic centers allowed the development of a mask that inactivates the virus that causes covid-19, endorsed by the João Lobo Antunes Institute of Molecular Medicine (iMM), in Lisbon, according to the EFE agency.
The mask, called MOxATech, has been on sale since April, but its ability to inactivate the virus has only been confirmed now by a series of tests carried out by the institute, informed the entities that are part of the project today.
This protective equipment, which has a coating that neutralizes the virus when it comes into contact with it, was developed thanks to the collaboration between the textile manufacturer Adalberto, the retail company MO, Sonae Fashion, the technology center CITEVE, iMM and Universidade do Minho.
Virologist Pedro Simas, who coordinated the work, said that the tests “showed an effective inactivation of SARS-CoV-2 even after 50 washes, observing a 99% viral reduction after one hour of contact with the tissue”.
To test its effectiveness, the tissue was analyzed after contacting a solution containing a certain amount of virus, to measure its viability over time.
Before iMM confirmed its effectiveness in inactivating covid-19, the Institut Pasteur de Lille, France, had already successfully tested its antimicrobial properties against the H1N1 virus, the corona and rotavirus type.
The mask, developed with a technical fabric that integrates several different layers, waterproof and reusable, also has a certification from the French Direction Générale des Entreprises, which certifies a 96% particle retention, even after 50 washes.
Although they are now on sale only in the stores of the Portuguese brand MO, available throughout the European Union, the project was opened to the community so that other brands in Portugal and abroad can distribute them.
The price of the mask, on the MO website, is 10 euros – or R $ 61.
