In a chromatograph, a separation column is disposed between an injection system and a detector. The separation column includes a bundle of capillaries which are formed of carbon nanotubes with a typical diameter of 0.5 nm to 5 nm and may number in the several hundreds.

Opinion: Complex Nanotube Circuits
1) Grow the nanotubes on a separate substrate, then stamp them onto the circuit. This lets the circuit stay at low temperatures. By contrast, nanotubes are single, precise molecules being assembled to build up useful larger systems. This is a lot closer to the original meaning of the word.
