Scientists build atom-scale sub that moves at 'breakneck' speeds
There are still no nanobots plying our bloodstreams, seeking and destroying cancer and other diseases. However, scientists at Rice University have just built a molecule-scale "submarine," so that's a pretty positive step towards "Fantastic Voyage." Mades at the same lab that developed "nanocars," the devices are a mere 244 atoms in size, with motors powered by ultraviolet light that turn at over a million RPM. That propels them along at a solid one inch per second, which is a "breakneck" pace according to lab director James Tour. "These are the fastest-moving molecules ever seen in solution," he said.
