Nano-crane (IMAGE) Technical University of Munich (TUM) Caption Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. Electric fields drive molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanorobots fast enough to do assembly line work in future molecular factories.
