Until recently, scientists worried that the ability to build conducting wires on a nanoscale has lagged behind the accompanying research on nanotechnological devices. Researchers at the Institute for Surface and Interface Science at the University of California, Irvine, have announced that they can now mass-produce uniform conducting nanowires from 15 nanometers in diameter up to half a millimeter in length. Graphite is cut at an angle to create uniform steps in a crystal lattice. Then, using electrodeposition, molybdenum oxide crystals are coaxed to grow on the edges of the lattice and diameter is controlled by timing the deposition. The wires, removed from the lattice, can be bent without breaking.
