Inactivation and spike protein denaturation of novel coronavirus variants by CuO/TiO nano-photocatalysts.

In order to reduce infection risk of novel coronavirus (SARS-CoV-2), we developed nano-photocatalysts with nanoscale rutile TiO (4-8 nm) and CuO (1-2 nm or less). Their extraordinarily small size leads to high dispersity and good optical transparency, besides large active surface area. Those photocatalysts can be applied to white and translucent latex paints.
