German Researchers Furnish DNA with Nano "Wire"
The DNA biomolecule, responsible in nature for storing hereditary information, is being used increasingly as a component in nanotechnology. One successful approach for producing functional nanostructures from DNA is to insert metal ions into an artificial DNA double helix, which serves as a framework. "If several metal ions are arranged next to each other in this way," says Prof. Jens Müller from the Institute of Inorganic and Analytical Chemistry at WWU, "a molecule is produced which incorporates, so to speak, a one-dimensional wire." Together with researchers from the University of Zurich, his team has now produced an artificial DNA with a razor-thin "wire" inside, demonstrating in the process that the natural structure is preserved. The results of their research are presented in the current online edition of the prestigious magazine "Nature Chemistry". Before the artificial DNA can be used in future as a nanowire or nanomagnet * or in analytics, e.g. to ascertain the existence of heavy metals in tap-water * further physical properties must first be examined in detail, now that the structure has been successfully clarified.
Hydromel projects has several activities running on nano-wire production and developments led by partner TYNDALL (IR).
