COVID-19 has shaped up to be one of the defining challenges of our lives. Among the primary modes of spread is surface to surface contamination. Under these circumstances, the shortcomings of traditional chemical agent-based disinfectants got more pronounced. A lack of regenerative properties and the short duration activity of traditional disinfectants impacted the efforts to contain the spread. Here we report photoactivated self-cleaning antiviral coating utilizing a Yttrium Orthosilicate-based up-conversion (visible to UV) nanomaterials. Our experiments have shown, UCNPs coated surfaces [Y2SiO5(1% Pr, 1% Gd)] has reduced active viral load (Coronavirus OC43) from 4*104 infectious units to 0 in 30 min and SARS-CoV-2 in 45 min. In addition, it has also shown antiviral properties against a range of viruses, including SARS-CoV-2, Rhinovirus, La Crosse virus, Vaccinia virus, Vesicular Stomatitis virus, Parainfluenza virus, and Zika virus.
