Scientists at the IBM Research Zurich Laboratory in collaboration with the ETH Zurich have succeeded in positioning so-called nanotubes measuring only 25 by 80 nanometers on a surface in a highly precise and systematic manner using a special nanoscale orientation and printing process. To prove that their method works, the scientists constructed a standing and a walking Ampelmännchen (pedestrian pictogram on traffic lights) of selectively oriented gold nanotubes. An interesting application of this method could be as counterfeit-proofing of valuable items such as watches, jewellery or works of art.
