Watching viruses fail to pass through face masks

Using a new analytical method, Empa researchers have tracked viruses as they pass through face masks and compared their failure on the filter layers of different types of masks. The new method should now accelerate the development ...

New knowledge about airborne virus particles could help hospitals

The risk of being exposed to COVID-19 particles increases with shorter physical distance to a patient, higher patient viral load and poor ventilation. Measurements taken by researchers at Lund University in Sweden of airborne ...
