Researchers from the Universidad Católica de Valencia (UCV), from the Biomaterials and Bioengineering Group of CITSAM (Centro de Investigación Traslacional San Alberto Magno), led by Ángel Serrano, have developed a commercial tissue protection filter for masks, manufactured with a biofunctional coating of benzalkonium chloride, capable of inactivating SARS-CoV-2 after one minute of contact and multi-resistant bacteria.
Masks have been recognized worldwide as a preventive measure to prevent the disease. Although we know that other preventive measures must be taken in addition to masks, it is important to distinguish and mention that not all masks protect equally and their responsible use is key in the fight against this pandemic.
It is worth mentioning that commercial masks are made of materials that cannot inactivate SARS-CoV-2.
This new filter developed can also inactivate Staphylococcus aureus and Staphylococcus epidermidis, which are resistant to the antibiotic methicillin, and can aggravate coronavirus pneumonia and threaten people’s lives.
This makes the filter created by UCV scientists the first to inactivate SARS-CoV-2 and also multi-drug resistant bacteria. In the next few months, masks equipped with these new filters may have been put on the market at an affordable price because their manufacturing method is very fast and economical, and the key product benzalkonium chloride is not expensive.
