Rapid inactivation of SARS-CoV-2 by titanium dioxide surface coating.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission occurs via airborne droplets and surface contamination. Titanium dioxide (TiO ) coating of surfaces is a promising infection control measure, though to date has not been tested against SARS-CoV-2. : Virus stability was evaluated on TiO - and TiO -Ag (Ti:Ag atomic ratio 1:0.
