Beams of light used to “draw” three-dimensional nanostructures could give scientists more flexibility in creating tiny sensors and electronic components. The new technique, called Optically Directed Assembly, uses a low-power laser to form long filaments from dissolved gold and carbon particles only millionths of a millimeter in size. The energy of the laser fuses these pieces into structures that remain intact after the fluid is drained away, scientists at Argonne Nati...
