Atom Hauler

Atoms are everywhere, but you'd never know it. Even though these tiny building blocks of matter make up everything—from chairs to air—they're far too tiny to see with your own eyes. When scientists want to study atoms one at a time, however, they can use special, highly sensitive microscopes to see them. Using these tools, called scanning tunneling microscopes (STMs), researchers can also move individual atoms around. Now, researchers in France and Germany have taken the technology one step further. They have found a way to gather up and move around atoms in bunches. Their work may help them eventually make and operate tiny, nanoscale machines.The key part of a scanning tunneling microscope is an extremely sharp needle that rides over the surface being examined. This sharp tip can even nudge a single atom from one place to another. But maneuvering more than one atom at a time is a difficult juggling act. To make the task easier, the researchers created a new, six-legged molecule. They called it hexa-t-butyl-hexaphenylbenzene (HB-HBP). The molecule is shaped like a hexagon (having six sides) and contains rings of carbon atoms. Six tripodlike feet support the structure. Like a minuscule vacuum cleaner, it can easily slide over a copper surface, sucking up loose copper atoms. Experiments performed at very low temperatures and in practically airless conditions showed that an STM tip can move an HB-HBP molecule that holds as many as five copper atoms that the molecule has picked up. Scientists can then use the STM tip to lift the carrier molecule, leaving the clump of atoms behind. The development is a major step toward making molecule-sized machines, scientists say. Someday, tiny sweepers might gather atoms together to form wires. Or they might pile atoms into regularly spaced mounds that, together, affect light or magnetic fields in useful ways.—E. Sohn
