VIDEO - Wire self-assembly in three dimensions

Nanotechnology may be the key to continued shrinking of electronic circuits, but the difficult is fabrication. Making nanowires is hard enough, but making nanowires into usable circuits is even more difficult. Because actual fabrication is difficult or impossible at such small scales, most researchers are turning to self-assembly, many using the self-assembling properties of diblock copolymers. Recently, researchers at MIT have successfully controlled the self-assembly of these wires in three dimensions, a critical step towards wide-scale nanowire fabrication.
