Abstract (en)
[origin: WO2022018678A1] The invention relates to the use of nitrogen-doped TiO2 (TiO2-N) nanoparticles activatable by UV light and/or visible light and/or sunlight, of a substrate nanofunctionalised with said nanoparticles and of a device comprising said substrate and at least one light source configured to emit radiation having a wavelength comprised between 10 and 1500 nm, for killing a virus and/or fungi and/or bacteria. The invention also relates to a method for killing said virus and/or said fungi and/or said bacteria, comprising the steps of: (A) providing said nanoparticles or (A') said substrate or (A") said device; (B) placing said nanoparticles or (B') said substrate or (B") said device in contact with said virus and/or said fungi and/or said bacteria; and (C) irradiating said nanoparticles or (C')/(C") said substrate with a source of UV light and/or visible light and/or sunlight.
