Growing Wires In Water

moooooooo writes: "Australia's ABC is reporting that U.S. researchers have discovered a new way to grow microscopic electrical wires in water, and soon hope to be plugging into living cells. Kevin D. Hermanson and colleagues from the University of Delaware created self-assembling, self- repairing conductive wires -- a micrometre in diameter and 5 mm in length -- by suspending gold particles in water between two electrodes."
