Claims12
A method for inactivating a human virus, the method comprising contacting the virus with an object comprising a powder comprising silicon nitride at a concentration from about 1 wt. % to about 30 wt. %, wherein the powder has an average particle size of 0.6 μm to 5 μm, wherein the silicon nitride successively binds and inactivates at least 99% of the virus, and wherein the object is a protective gown, a body cover, a head cover, a shoe cover, a face mask, a face shield, an eye protector, gloves, a surgical gown, a surgical drape, a cubicle curtain, a face mask filter, a respirator filter, an air filtration filter, an air ventilation filter, a knob, a handle, a railing, a bed frame, a bed tray, a table, a chair, an equipment rack, a cabinet, or a cart wherein the virus is not SARS-CoV-2.
A method for inactivating a human virus, the method comprising contacting the virus with a composition comprising a powder comprising silicon nitride at a concentration from about 1 wt. % to about 30 wt. %, wherein the powder has an average particle size of 0.6 μm to 5 μm, wherein the silicon nitride successively binds and inactivates at least 99% of the virus wherein the virus is not SARS-CoV-2.
An article of personal protective equipment (PPE) having antiviral properties, the article comprising a powder comprising silicon nitride at a concentration from about 1 wt. % to about 30 wt. % embedded in or coated onto a surface of the article, wherein the powder has an average particle size of 0.6 μm to 5 μm, wherein the silicon nitride binds and inactivates at least 99% of a human virus wherein the virus is not SARS-CoV-2.
