Piecework at the nano assembly line

Fast computer control for molecular machines

22-Jan-2018 - Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line ...

Nanocars taken for a rough ride

If you're driving a nanocar on the open road, things are bound to get sticky

03-Jun-2016 - Rice University researchers who developed the first nanocars and colleagues at North Carolina State University found in recent tests that driving their vehicles in ambient conditions - exposed to open air, rather than a vacuum - got dicey after a time because the hydrophobic single-molecule cars ...
