Scientists have recruited DNA to manufacture minuscule wires that could be used for nanoscale electronic devices. According to a report published online this week by the Proceedings of the National Academy of Sciences, tiny tubes that self-assemble can be coated in metal to form highly conductive wires.

Thomas LaBean of Duke University and his colleagues first assembled tiles from synthetic DNA molecules, which they used as building blocks. Under the right chemical conditions, these tiles arrange themselves into tubes that measure just 25 nanometers in diameter and up to 20 microns in length. (The new process improves on previous assembly methods, which resulted in tubes of greatly varying lengths and some leftover tiles.) The scientists then created smooth, uniform silver nanowires from the tubes through a two-step chemical reaction

Just some cool shit that goes a long to proving that yes, Virginia, we're in the future. Guy at work showed me an article about this this morning. Nifty.
