Surfaces can be designed with antiviral properties to mitigate COVID-19

(American Institute of Physics) If a respiratory droplet from a person infected with COVID-19 lands on a surface, it becomes a possible source of disease spread, because while 99.9% of the droplet's liquid content evaporates within minutes, a residual thin film that allows the virus to survive can be left behind. In Physics of Fluids, researchers explore how the evaporation rate of residual thin films can be accelerated by tuning surfaces' wettability and creating geometric microtextures on them.
