Single molecule motor is the world's smallest
Scientists have created the world's smallest electric motor, made from a single molecule.
The tiny gadget is expected to lead to new devices that can be used in medicine and engineering.
The microscopic motor is just one nanometre across, about 60,000 times smaller than the width of a human hair.
The scientists, who describe their achievement in the journal 'Nature Nanotechnology', used a state-of-the-art low temperature scanning tunnelling microscope, which uses electrons instead of light to "see" molecules.
The scientists plan to submit their invention to the Guinness World Records.
