Abstract
A method of inactivating a virus that includes the step of contacting a virus with an antiviral composition comprising a hybrid antiviral metal-associated amyloid fibril comprising metal nanoparticles on a surface of an amyloid fibril to contact a virus and an antiviral composition comprising metal nanoparticles on a surface of an amyloid fibril wherein the antiviral composition removes virus and bacterial contaminants in water or air to non-detectable levels when water or air comes into contact with the antiviral composition.
Claims23
A water or air filtration apparatus comprising a support material that holds on or within it an antiviral composition comprising metal nanoparticles on a surface of an amyloid fibril thereby forming a hybrid antiviral metal-associated amyloid fibril and wherein the metal nanoparticles are a metal nanoparticle chosen from the group consisting of a silver nanoparticle, an iron hydroxide nanoparticle, an iron oxide nanoparticle and mixtures thereof.

19-20. (canceled)
A filtration apparatus comprising an antiviral composition comprising metal nanoparticles on a surface of an amyloid fibril and a housing that contains the antiviral composition and wherein the antiviral composition has synergistic antiviral properties compared to the amyloid fibrils alone and the antiviral composition removes virus and bacterial contaminants in water or air to non-detectable levels when water or air comes into contact with the antiviral composition;
- wherein the amyloid fibril is an amyloid fibril chosen from the group consisting of:
- a beta-lactoglobulin, whey, lysozyme, bovine serum albumin, soy proteins, ovalbumin and mixtures thereof;
- and
- wherein the metal nanoparticles have a particle size of from about 5 nm to about 900 nm and are chosen from the group consisting of a silver nanoparticle, an iron hydroxide nanoparticle, an iron oxide nanoparticle and mixtures thereof.
22-121. (canceled)
A heating, ventilation, and air conditioning system associated with a vehicle, an interior volume of a structure, or a portion of the interior volume of a structure, the heating, ventilation, and air conditioning system comprising:
- a water filtration apparatus or air filtration apparatus comprising a support material holding an antiviral composition on or within the support material, the antiviral composition comprising metal nanoparticles on a surface of an amyloid fibril thereby forming a hybrid antiviral metal-associated amyloid fibril and wherein the metal nanoparticles are a metal nanoparticle chosen from the group consisting of a silver nanoparticle, an iron hydroxide nanoparticle, an iron oxide nanoparticle and mixtures thereof.
