The bandage includes a cloth layer portion including a first silver treatment including a first silver concentration; and an adhesive layer upon a bottom surface of the cloth layer portion configured to adhere the bandage to skin of a wearer. The bandage further includes an absorbent pad portion comprising a second silver treatment including a second silver concentration lower than the first silver concentration. ## Claims ### Claim 1 A bandage including at least two portions with different concentrations of silver treatment upon the at least two portions of the bandage, the bandage comprising: a cloth layer portion comprising: two side tab portions and one central portion provided therebetween, a first silver treatment including a first silver concentration of between 5-15%, wherein the first silver treatment is operable to release silver ions to skin around a wound site of a wearer; and an adhesive layer provided upon a bottom surface of each of the side tab portions of the cloth layer portion and configured to adhere the bandage to the skin around the wound site without contacting the wound site; an absorbent pad portion provided on a bottom surface of the central portion of the cloth layer portion such that the absorbent pad portion is operable to contact the wound site of the wearer and separate the cloth layer portion from the wound site of the wearer during use of the bandage, the absorbent pad portion comprising a second silver treatment including a second silver concentration of 1%-2%, wherein the second silver concentration is lower than the first silver concentration and the second silver treatment is operable to release silver ions directly to the wound site; wherein the first silver treatment has a relatively higher silver concentration than the second silver treatment so that the cloth layer portion provides a reservoir of silver that can propagate outwardly from the bandage over time to release silver ions to the skin around the wound site and provide antimicrobial properties to the skin around the bandage. ### Claim 2 (depends on 1) The bandage of claim 1, wherein the cloth layer portion comprising the first silver treatment comprises a layer of silver material upon a top surface of the cloth layer portion. ### Claim 3 (depends on 2) The bandage of claim 2, wherein the layer of silver material comprises one of an electroless plating layer, a sputtering deposit layer, a dip coating layer, and a nano-coating layer. ### Claim 4 (depends on 1) The bandage of claim 1, wherein the absorbent pad portion comprises: a pad constructed with an absorbent material; a net layer material encapsulating the pad constructed with the absorbent material; and a layer of silver material upon the net layer material. ### Claim 5 (depends on 4) The bandage of claim 4, wherein the layer of silver material comprises one of an electroless plating layer, a sputtering deposit layer, a dip coating layer, and a nano-coating layer. ### Claim 6 (depends on 1) The bandage of claim 1, wherein the cloth layer portion comprising the first silver treatment comprises silver treated threads. ### Claim 7 (depends on 1) The bandage of claim 1, wherein the first silver treatment is deposited about a perimeter of the cloth layer portion. ### Claim 8 (depends on 1) The bandage of claim 1, wherein the first silver treatment is limited to a perimeter of the cloth layer portion. ### Claim 9 (depends on 1) The bandage of claim 1, wherein the second silver treatment comprises a layer of silver having a thickness of less than 100 nanometers. ### Claim 10 (depends on 1) The bandage of claim 1, wherein the second silver treatment comprises a layer of silver having a thickness of between 100 nanometers and 500 nanometers. ### Claim 11 (depends on 1) The bandage of claim 1, wherein the second silver treatment comprises a layer of silver having a thickness of between 500 nanometers and 1 micron. ### Claim 12 (depends on 1) The bandage of claim 1, wherein the second silver treatment comprises a layer of silver having a thickness of between 1 micron and 15 microns. ### Claim 13 (depends on 1) The bandage of claim 1, wherein the second silver treatment comprises a layer of silver having a thickness of between 15 microns and 30 microns. ### Claim 14 (depends on 1) The bandage of claim 1, wherein the second silver treatment comprises a layer of silver having a thickness of between 30 microns and 45 microns. ### Claim 15 (depends on 1) The bandage of claim 1, wherein the absorbent pad portion comprises: a pad constructed with an absorbent material; a net layer material encapsulating the pad constructed with the absorbent material; and a silver material provided within the absorbent material.
