Claims12
A virus-removing filter for removing air-suspended virus from air comprising
- a filter material allowing air to pass therethrough and thereby remove air-suspended virus from air during passage therethrough and
- a virus-capturing body on or within said filter material, said virus-capturing body selected from the group consisting of sialic acid, a sialic acid derivative, a sugar containing sialic acid and/or a sialic acid derivative, a glycoprotein containing sialic acid and/or a sialic acid derivative, a glycolipid containing sialic acid and/or a sialic acid derivative, and mixtures thereof.
A virus-removing filter for removing air-suspended virus from air comprising
- a filter material allowing air to pass therethrough and thereby remove air-suspended virus from air during passage therethrough and
- a virus-capturing body attached to or on or within said filter material, said virus-capturing body being a substrate having impregnated therein or kneaded therein a member selected from the group consisting of sialic acid, a sialic acid derivative, a sugar containing sialic acid and/or a sialic acid derivative, a glycoprotein containing sialic acid and/or a sialic acid derivative, a glycolipid containing sialic acid and/or a sialic acid derivative, and mixtures thereof.
A virus-removing filter for removing air-suspended virus from air comprising
- a filter material allowing air to pass therethrough and thereby remove air-suspended virus from air during passage therethrough and
- a virus-capturing body attached to or on or within said filter material, said virus-capturing body being a material having covalently bonded thereto a member selected from the group consisting of sialic acid, a sialic acid derivative, a sugar containing sialic acid and/or a sialic acid derivative, a glycoprotein containing sialic acid and/or a sialic acid derivative, a glycolipid containing sialic acid and/or a sialic acid derivative, and mixtures thereof.
A virus-removing filter for removing air-suspended virus from air comprising
- a filter material allowing air to pass therethrough and thereby remove air-suspended virus from air during passage therethrough and
- a virus-capturing body attached to or on or within said filter material, said virus-capturing body being a polymerized/copolymerized material formed by polymerizing and/or copolymerizing a styrene monomer and/or an acrylamide monomer, either or both monomers having incorporated into a member selected from the group consisting of sialic acid, a sialic acid derivative, a sugar containing sialic acid and/or a sialic acid derivative, a glycoprotein containing sialic acid and/or a sialic acid derivative, a glycolipid containing sialic acid and/or a sialic acid derivative, and mixtures thereof.
