*** ABOVE CREDIT MUST BE PRINTED IN FULL *** World's smallest electrical wire. Coloured Atomic Force Micrograph (AFM) tapping-mode image of a carbon nanotube wire (blue) on platinum electrodes (yellow). The nanotube is 1. 5 nanometres across, a mere 10 atoms wide. It was made by firing a laser at a mixture of carbon, nickel and cobalt to make spherical carbon fullerene molecules join together to form a tube. Besides the potential to miniaturise electronic components, the nanotube's small size gives it special properties that could be used to make entirely new devices. Magnification: x120,000 at 5x7cm size.
