20 .- 27 . (canceled)

28 . The article of claim 1 , further comprising an adhesive layer between the substrate and the superhydrophobic or superoleophobic portion.

29 .- 30 . (canceled)

31 . The article of claim 1 , wherein a contact angle of the superhydrophobic or superoleophobic article is at least 120 degrees, as determined using ASTM D7334-08.

32 .- 34 . (canceled)

35 . The article of claim 1 , wherein the substrate is flexible.

36 . The article of claim 1 , wherein the superhydrophobic or superoleophobic portion, the substrate, or both are transparent.

37 . The article of claim 1 , wherein the superhydrophobic or superoleophobic portion, the substrate, or both comprise a pigment, a fluorophore, or both.

38 .- 39 . (canceled)

40 . The article of claim 1 , wherein the superhydrophobic or superoleophobic portion comprises a button, a trigger, or a combination thereof.

41 .- 43 . (canceled)

44 . An article comprising:
a substrate comprising a visual indicia; and a superhydrophobic or superoleophobic portion disposed on a surface of the substrate, wherein
the superhydrophobic or superoleophobic portion a button, a trigger, a graphical user interface, the visual indicia, or a combination thereof is substantially transparent or substantially translucent allowing the visual indicia of the substrate to be visible therethrough, and
the article comprises a medical device, a treatment device, or a surgical device.

45 .- 53 . (canceled)

54 . The article of claim 44 , wherein the superhydrophobic or superoleophobic portion comprises a microstructure, a nanostructure, or a combination thereof.
