Self-sterilizing polymers are effective at inactivating SARS-CoV-2 virus Researchers from North Carolina State University, Boston University, and Kraton Corporation have demonstrated a family of self-sterilizing polymers that are effective at inactivating coronaviruses, including SARS-CoV-2 - the virus that causes COVID-19. The work opens the door to a suite of applications that could help to reduce the transmission of COVID-19 and other diseases. "Our work here provides conclusive evidence that these materials, anionic polymers, can inactivate human coronaviruses quickly and efficiently," says Richard Spontak, co-author of a paper on the work accepted for publication in Advanced Science. Spontak is a Distinguished Professor of Chemical and Biomolecular Engineering and a professor of materials science and engineering at North Carolina State University.
