The anti-microbial composition may be used to kill, inhibit growth, mitigate, and/or inhibit retention of one or more microbes and/or bacteria. The anti-microbial properties of the composition may be provided by a microbial inhibition material, which comprises a silane compound (e.g., a first silane compound) functionalized with a metal ion. The composition may also include a fingerprint inhibition material, which comprises a silane compound (e.g., a second silane compound) that may preferably be hydrophobic. The fingerprint inhibition material may comprise an invisible fingerprint material and/or an anti-fingerprint material. The invisible fingerprint material is configured to hide fingerprints by making them optically less visible (e.g., to the human eye), while the anti-fingerprint material may be configured to suppress the retaining of fingerprints. In addition to providing anti-microbial and anti-fingerprint properties, the composition may also be chemically inert, mechanically robust, and/or optically transparent. ## Claims ### Claim at position 1 1-54: (canceled) ### Claim 55 An anti-microbial coating, comprising: a microbial inhibition material comprising a silane compound and one or more metal ions, wherein the silane compound comprises two or more functional groups bound to the one or more metal ions, and wherein the two or more functional groups comprise: (i) a first functional group selected from the group consisting of an amine group, a diamine group, a triamine group, and combinations thereof; and (ii) a second functional group comprising a hydroxyl group. ### Claim 56 (depends on 55) The anti-microbial coating of claim 55, wherein the amine group comprises a primary amine group. ### Claim 57 (depends on 55) The anti-microbial coating of claim 55, wherein the amine group comprises an ethanolamine group. ### Claim 58 (depends on 55) The anti-microbial coating of claim 55, wherein the amine group comprises a secondary amine group. ### Claim 59 (depends on 55) The anti-microbial coating of claim 55, wherein the amine group comprises a tertiary amine group. ### Claim 60 (depends on 55) The anti-microbial coating of claim 55, wherein the diamine group comprises ethylenediamine, diethylenediamine, and/or triethylenediamine. ### Claim 61 (depends on 55) The anti-microbial coating of claim 55, wherein the diamine group comprises a thiourea group. ### Claim 62 (depends on 55) The anti-microbial coating of claim 55, wherein the hydroxyl group comprises an ethanolamine group. ### Claim 63 (depends on 55) The anti-microbial coating of claim 55, wherein the one or more metal ions comprise silver, copper, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zinc, zirconium, palladium, cadmium, platinum, gold, mercury, terbium, tungsten, aluminum, gallium, germanium, arsenic, selenium, tin, antimony, tellurium, lead, bismuth, and/or combinations thereof. ### Claim 64 (depends on 55) The anti-microbial coating of claim 55, wherein the one or more metal ions comprise silver. ### Claim 65 (depends on 55) The anti-microbial coating of claim 55, wherein the one or more metal ions comprise copper. ### Claim 66 (depends on 55) The anti-microbial coating of claim 55, wherein the anti-microbial coating has a greater than or equal to 99% reduction in retention of a microbe after the anti-microbial coating is exposed to the microbe. ### Claim 67 (depends on 66) The anti-microbial coating of claim 66, wherein the microbe is of the genus Escherichia, Staphylococcus, Streptococcus, Listeria, Enterococcus, Salmonella, and/or Pseudomonas. ### Claim 68 (depends on 66) The anti-microbial coating of claim 66, wherein the microbe comprises Escherichia coli and/or Staphylococcus aureus. ### Claim 69 (depends on 55) The anti-microbial coating of claim 55, wherein the silane compound is a first silane compound, and the antimicrobial coating further comprises a fingerprint inhibition material comprising a second silane compound. ### Claim 70 (depends on 55) The anti-microbial coating of claim 55, wherein the anti-microbial coating has a water contact angle between greater than or equal to 45° and less than or equal to 65° after enduring between greater than or equal to 1,500 abrasion cycles and less than or equal to 4,500 abrasion cycles. ### Claim 71 (depends on 55) The anti-microbial coating of claim 55, wherein the anti-microbial coating has a diiodomethane contact angle between greater than or equal to 35° and less than or equal to 45° after enduring between greater than or equal to 1,500 abrasion cycles and less than or equal to 4,500 abrasion cycles. ### Claim 72 (depends on 55) An article comprising: The anti-microbial coating of claim 55. ### Claim 73 (depends on 72) The article of claim 72, wherein the anti-microbial coating is disposed on a substrate. ### Claim 74 (depends on 73) The article of claim 73, wherein the substrate comprises glass, a ceramic, a metal, a metal oxide, and/or a polymer. ### Claim 75 (depends on 70) The article of claim 70, wherein the article comprises a cell phone, a computer monitor, a television screen, a touch screen, an appliance, a transportation vehicle, and/or building equipment.
