-enhanced shockwave generation, which alters virus membrane and/or surface groups and, therefore, reduces virus binding and fusion with the host cell.190 Inactivation of SARS-CoV-2 by Photocatalytic Nanoparticles Photocatalytic NPs offer another possible approach to the inactivation of SARS-CoV-2. The most described NP in this category is titanium dioxide (TiO2), which shows photocatalytic properties when illuminated under UV light, is considered inert, has low toxicity,
