Brazilian scientist creates products that inactivate the coronavirus in 30 seconds
Since the beginning of the pandemic, the global industry has been working on the search for new technologies to mitigate the effects of the new coronavirus. An example of this is antiviral fabrics, such as the one pioneered by the Brazillian group Dalila Têxtil led by Alexsandra Valério, doctor in Chemical Engineering by UFSC. The technology behind the antiviral uses silver particles.
“When the material comes in contact with the virus, it ends up breaking the viral layer and exposing the virus’s DNA or RNA. It then no longer has its action when it infects a cell”, explains Alexsandra Valério, one of those responsible for the development of the material.
The effectiveness of the product has already been proven by several tests and laboratory certifications and does not offer any risk of toxicity to health, guaranteeing a dermatologically tested seal, some tests proved that it can deactivate the virus in less than 30 seconds. However, many people wonder about the sustainability of this material.
The Chemical engineer explains that the silver particles used to make the fabric are easily precipitated in the effluents, as they react with flocculants applied to eliminate the sludge and, after the silver has reacted and become a salt in the effluent, biologically it is not antimicrobial anymore. In addition, it was thought about the post-use of the material.
“As it is a high quality fabric, it has a longer useful life and can remain in use for a longer time, helping to preserve the environment and saving resources”, adds the director of Dalila Têxtil, André Klein.
Today the effectiveness of this product extends to 50 washes and new tests are underway.
