- 34. The method of claim 32, wherein the tube comprises a polymer.
- 35. The method of claim 1, wherein the surface is a planar surface.
- 36. A method, comprising:
introducing a first gas composition into a tube, the first gas composition comprising a first compound that is substantially inert with respect to a first material forming the inner surface of the tube; and exposing the first gas composition to conditions sufficient to change the first compound into a second compound reactive with the first material and to deposit a layer of a second material on the inner surface of the tube.
- 37. The method of claim 36, wherein exposing the first gas composition to conditions sufficient to change the first compound into a second compound comprises activating a plasma in the first gas composition.
- 38. The method of claim 37, wherein activating the plasma comprises exposing the first gas composition to electromagnetic radiation.
