Northwestern Engineering’s Jiaxing Huang has received funding to develop a new self-sanitizing medical face mask that deactivates viruses on contact. The project received a rapid response research (RAPID) grant from the National Science Foundation (NSF), which has called for immediate proposals that have potential to address the spread of novel coronavirus (COVID-19) with better personal protective equipment (PPE).

“Spread of infectious respiratory diseases, such as COVID-19, typically starts when an infected person releases virus-laden respiratory droplets through coughing or sneezing,” said Huang, professor of materials science and engineering, who leads the research. “To further slow and even prevent the virus from spreading, we need to greatly reduce the number and activity of the viruses in those just released respiratory droplets.”

To reduce the number and activity of viruses, Huang’s team is investigating anti-viral chemicals that can be safely built into masks to self-sanitize the passing respiratory droplets. (The lab members have been designated as “essential researchers” during the State of Illinois’ “stay-at-home” order.)

Current masks worn by individuals provide a physical barrier, reducing the number of escaped respiratory droplets that would become a new source of infection after entering the atmosphere or landing on objects and surfaces.

Huang aims to design a drop-in solution that works generically with current, various types of masks to provide an additional function of deactivating viruses. The mask would help reduce the level of viruses in the droplets exhaled by infected wearers and better protect the healthcare workers or others around them.

“More researchers — and especially students in the physical sciences and engineering — can proactively study the problems and think of new ways to mitigate the transmission and spread of viruses,” Jiaxing Huang said. “Even those who need to stay home for now can still continue to brainstorm.”
