What if preventing respiratory illnesses such as COVID-19 and influenza was as easy as a quick spritz of nasal spray every morning?
Numerous bacteria and viruses, including those that cause COVID-19 and influenza, enter the body through the lungs when people breathe, resulting in illness. Johns Hopkins engineers have created thin, thread-like strands of molecules called supramolecular filaments that are designed to be sprayed into the nose, blocking those harmful viruses from entering the lungs.
“The idea is that the filaments will work like a sponge to absorb the COVID-19 virus and other viruses before they have the chance to bind to cells in our airways. Even if the therapeutic can block the virus for an hour or two, that can be helpful when people must be in a public setting,” said research team leader Honggang Cui, core researcher at the Institute for NanoBioTechnology and associate professor of chemical and biomolecular engineering at Johns Hopkins Whiting School of Engineering.
The team’s results appeared recently in Matter, and the work was done through a collaboration with Hongpeng Jia, assistant professor of surgery, and other researchers at Johns Hopkins School of Medicine.
