College of Cincinnati biologists have discovered {that a} double layer of silk together with a surgical masks can improve its capability to forestall the unfold of viruses like COVID-19.

UC biologist Patrick Guerra, UC biologist Theresa Culley, UC postdoctoral researcher Adam Parlin, now at SUNY-ESF, and UC graduate pupil Samuel Stratton, now on the College of Michigan, started investigating silk instead face masks materials at the beginning of the COVID-19 pandemic in 2020 when private protecting tools such because the N95 face masks was in brief provide.

UC researchers discovered that double masking with a silk face masks additionally helps lengthen the lifetime of surgical masks with out impeding an individual’s capability to breathe comfortably.

The research was printed within the journal Aerosol and Air High quality Analysis.

“Persons are nonetheless utilizing surgical masks to guard others and themselves. However they are often unfastened on the sides and across the nostril,” stated Guerra, an assistant professor of biology in UC’s Faculty of Arts and Sciences.

Guerra and his colleagues collaborated with researchers with the UC Faculty of Drugs’s Middle for Well being-Associated Aerosol Research.

As circumstances of COVID-19 start to extend throughout the USA, extra individuals are reaching for masks once more to guard themselves and people round them.

“On the time of our research, private protecting tools was at a premium when it comes to availability due to supply-chain points,” Guerra stated. “Folks had been having to reuse their masks.”

Masks have gotten a rising supply of litter around the globe.

“They take a protracted, very long time to degrade,” Guerra stated.

So taking full benefit of every masks’s helpful lifespan can assist stop waste, he stated.

Guerra research the superb properties of silk in his biology lab. Silk fiber has antimicrobial properties. And silk is hydrophobic, which suggests it sheds water not like cotton masks that sometimes take in it.

And silk is way extra breathable than cotton.

“We confirmed {that a} silk masks does not improve the burden of respiratory when utilized in a double layer with a surgical masks. It wasn’t uncomfortable,” Guerra stated. “And it enhances the power of surgical masks to do their job.”
