The mass production of nanoscale devices could be a step closer following the construction of a nanoscale conveyor belt made of carbon nanotubes.

By applying a small electrical current to a carbon nanotube, researchers from the Lawrence Berkeley National Laboratory in Berkeley, California moved indium particles along the tube like auto parts on an assembly line.

“We’re not transporting atoms one at a time anymore—it’s more like a hose,” says Berkeley researcher Chris Regan.
