Abstract
Official abstract text for this publication.
An agent for virus inactivation capable of exhibiting inactivation action based on structural destruction such as degradation and decomposition against viruses, which comprises a monovalent copper compound such as cuprous oxide, cuprous sulfide, cuprous iodide, and cuprous chloride as an active ingredient, and a virus inactivation material, which contains the agent for virus inactivation on a surface of a substrate and/or inside of the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for inactivating a virus comprising contacting the virus in a dark place with a TiO 2 particle that carries on its surface a nanocluster of a mixture containing a monovalent copper oxide and a divalent copper oxide, wherein contact of the virus with the particle in the dark results in virus inactivation under dark conditions. 2. The method for inactivating a virus according to claim 1 , wherein the monovalent copper compound is in the form of microparticles. 3. The method for inactivating a virus according to claim 1 , comprising contacting the virus with the TiO 2 particle and at least one other visible-light-responsive photocatalytic substance. 4. The method for inactivating a virus according to claim 1 , wherein the TiO 2 particle is on a surface and/or inside of a substrate. 5. The method for inactivating a virus according to claim 4 , wherein the TiO 2 particle is on the surface of the substrate and immobilized using a binder. 6. The method for inactivating a virus according to claim 4 , wherein a dispersion comprising the TiO 2 particle dispersed in a resin is coated on the surface of the substrate and is cured. 7. The method according to claim 3 , wherein the at least one other visible-light-responsive photocatalytic substance is tungstic oxide. 8. The method according to claim 1 , wherein the dark place is the inside of a machine. 9. The method according to claim 1 , wherein the dark place is the inside of a refrigerator. 10. The method according to claim 1 , wherein the dark place is a darkened room. 11. The method according to claim 10 , wherein the dark place is a darkened hospital room. 12. The method according to claim 11 , wherein the dark place is a darkened hospital waiting room. 13. The method according to claim 11 , wherein the dark place is a darkened hospital operating room.
