SciTechDaily: Silk offers homemade solution for COVID-19

UC biologist Patrick Guerra found that silk prevents infection better than other fabrics

SciTechDaily highlighted a study by the University of Cincinnati that concluded that silk masks were better at preventing infection from COVID-19 than cotton or synthetic fibers.

UC assistant professor Patrick Guerra and postdoctoral researcher Adam Parlin found that in the absence of a single-use N95 respirator or a surgical mask, homemade masks made of silk were a good alternative. Silk face masks are comfortable, breathable and repel moisture, which is a desirable trait in fighting an airborne virus. 

Silkworms that eat mulberry leaves produce silk containing copper, which has natural virus-killing properties.

The study was published in the journal PLOS One.

“We’re trying to address this critical problem. Health care workers still don’t have enough personal protective equipment, namely N95 respirators or basic surgical masks,” Guerra said.

Discovery Amplified expands research, teaching support across A&S

February 19, 2026

The College of Arts & Sciences is investing in a bold new vision for research, teaching and creative activity through Discovery Amplified. This initiative was launched through the Dean’s Office in August 2024, and is expanding its role as a central hub for scholarly activity and research support within the Arts & Sciences (A&S) community. Designed to serve faculty, students, and staff, the initiative aims to strengthen research productivity, foster collaboration, and enhance teaching innovation. Discovery Amplified was created to help scholars define and pursue academic goals while increasing the reach and impact of A&S research and training programs locally and globally. The unit provides tailored guidance, connects collaborators, and supports strategic partnerships that promote innovation across disciplines.
