Title
(EN) NANOPARTICLES, NANOFUNCTIONALISED SUBSTRATE AND DEVICE WITH ANTIVIRAL AND/OR ANTIBACTERIAL AND/OR ANTIFUNGAL PHOTOCATALYTIC ACTIVITY
(FR) NANOPARTICULES, SUBSTRAT NANOFONCTIONNALISÉ ET DISPOSITIF À ACTIVITÉ PHOTOCATALYTIQUE ANTIVIRALE ET/OU ANTIBACTÉRIENNE ET/OU ANTIFONGIQUE
Abstract
(EN) 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.
(FR) L'invention concerne l'utilisation de nanoparticules de T1O2 dopé à l'azote (T1O2-N) activables par la lumière UV et/ou la lumière visible et/ou la lumière du soleil, d'un substrat nanofonctionnalisé avec lesdites nanoparticules et d'un dispositif comprenant ledit substrat et au moins une source de lumière conçue pour émettre un rayonnement ayant une longueur d'onde comprise entre 10 et 1 500 nm, pour tuer un virus et/ou des champignons et/ou des bactéries. L'invention concerne également un procédé destiné à tuer ledit virus et/ou lesdits champignons et/ou lesdites bactéries, comprenant les étapes consistant à : (A) fournir lesdites nanoparticules ou (A') ledit substrat ou (A") ledit dispositif; (B) mettre lesdites nanoparticules ou (B') ledit substrat ou (B") ledit dispositif en contact avec ledit virus et/ou lesdits champignons et/ou lesdites bactéries; et (C) irradier lesdites nanoparticules ou (C')/(C") ledit substrat avec une source de lumière UV et/ou de lumière visible et/ou la lumière du soleil.
