Abstract

We disclose a colorless composition comprising silver particles and water, wherein said particles comprise an interior of elemental silver and an exterior of ionic silver oxide, wherein the silver particles are present in the water at a level of about 5-40 ppm, and wherein the composition manifests significant antimicrobial properties including antiviral properties. Methods of use of the composition are described.

Claims (7)

1. A method for disinfecting surfaces contaminated with influenza A virus consisting essentially of the steps of:

providing an antiviral composition consisting essentially of a total concentration of silver of between about 5 and 40 parts per million in the form of colloidal silver metal particles produced by a method consisting of treating silver electrodes with alternating current and suspending in water, wherein the colloidal silver particles consist of interiors of elemental silver and surfaces of silver oxide and, wherein a majority of the colloidal silver particles consist of minimum diameters greater than 0.005 micrometers and maximum diameters less than 0.015 micrometers; and

contacting the surfaces with the composition for a time sufficient to inactivate the Influenza A virus thereon.

2. The method according to claim 1 , wherein the Influenza A is Avian Influenza A.

3. The method according to claim 2 , wherein the Avian Influenza A is Avian Influenza A (H3N2).

4. The method according to claim 1 , wherein the Influenza A is Human Influenza A.

5. The method according to claim 4 , wherein the Human Influenza A is Human Influenza A (H5N1).
