Coated, antimicrobial, chemically strengthened glass and method of making

An antimicrobial glass, comprising:

• a glass article having a surface;
• an ion exchange-derived, antimicrobial Ag+ region extending from the surface of the glass article to a depth of region in the glass article, the antimicrobial Ag+ region having a plurality of Ag+1 ions;
• and
• an ion exchange-derived, compressive stress layer extending from the surface of the glass article to a second depth in the glass article,
• wherein the concentration of the plurality of Ag+1 ions within 20 nm from the surface of the glass article is in the range of greater than or equal to 0.015 μg/cm2 to less than or equal to 0.08 μg/cm2 as measured by x-ray photoluminescence spectroscopy (XPS) or electron microprobe (EMP) analytical techniques, and
• further wherein the antimicrobial glass has a strength of at least 360 MPa based on a Ring on Ring test conducted after abrasion of the surface.

• an ion exchange-derived, compressive stress layer extending from the surface of the glass article to a second depth in the glass article;
• and
• a low surface energy coating on the surface of the glass article that allows water molecules to contact the antimicrobial Ag+ region,
• wherein the concentration of the plurality of Ag+1 ions within 20 nm from the surface of the glass article is in the range of greater than or equal to 0.015 μg/cm2 to less than or equal to 0.08 μg/cm2 as measured by x-ray photoluminescence spectroscopy (XPS) or electron microprobe (EMP) analytical techniques, and
