Two great buzzwords that work great together

This is interesting.

Carbon nanotubes have properties that make them very interesting as possible channel materials for advanced transistors. Unfortunately, precise placement of trillions of nanotubes is a difficult problem.

Enter DNA. DNA is very good at self-assembly, so it's (relatively) easy to make an array of DNA structures. It's also easy to modify a DNA molecule so that it will bind to, say, a carbon nanotube.

At least that's the idea behind recent work at IBM. So far they're still working on the DNA scaffold, but the potential is very cool.
