New Brunswick, N.J. (March 11, 2021) – Rutgers University–New Brunswick Professor Donald W. Schaffner is available for interviews on the likelihood of becoming infected by the SARS-CoV-2 coronavirus via shopping, groceries, surfaces and airborne/aerosol transmission after a year of lockdowns due to the global pandemic.…
COVID-19 Virus Survives on Surfaces Within Thin Film
To find out how the COVID-19 virus survives on surfaces, researchers in India are exploring the drying times of thin liquid films that persist on surfaces after most respiratory droplets evaporate. While the drying time of typical respiratory droplets is on the order of seconds, the survival time of the COVID-19 virus was found to be on the order of hours. In Physics of Fluids, the researchers describe how a nanometers-thick liquid film clings to the surface, allowing the virus to survive.
Plasma Treatments Quickly Kill Coronavirus on Surfaces
Researchers from UCLA believe using plasma could promise a significant breakthrough in the fight against the spread of COVID-19. In Physics of Fluids, modeling conducted showed strains of the coronavirus on surfaces like metal, leather, and plastic were killed in as little as 30 seconds of treatment with argon-fed, cold atmospheric plasma. The researchers used an atmospheric pressure plasma jet they built with a 3D printer to spray surfaces that were treated with SARS-CoV-2 cultures.
