Nanorods for New Nanostructured Materials
Scientists at Brookhaven National Laboratory have discovered that DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement, with the rods forming "rungs" on ladder-like ribbons linked by multiple DNA strands, results from the collective interactions of the flexible DNA tethers and may be unique to the nanoscale. The research, described in a paper published online in ACS Nano, a journal of the American Chemical Society, could result in the fabrication of new nanostructured materials with desired properties. In nanotechnology, nanorods are one morphology of nanoscale objects. Each of their dimensions range from 1-100 nm. They may be synthesized from metals or semiconducting materials. Nanorods are produced by direct chemical synthesis. Nanotechnology (nanotech) is the manipulation of matter on an atomic, molecular, and supramolecular scale.
