Surfaces Can Be Designed with Antiviral Properties to Mitigate COVID-19

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 a few minutes, a residual thin film that allows...
