The World's Smallest Car

Sunday, October 23, 2005

Using the parts inside a single molecule, scientists have constructed the world's smallest car. It has a chassis, axles and a pivoting suspension. The wheels are buckyballs, spheres of pure carbon containing 60 atoms apiece.
The whole car is no more than 4 nanometers across. That's slightly wider than a strand of DNA. A human hair is about 80,000 nanometers thick.
Other groups have made car-shaped nanoscale objects. But this is the first one that rolls "on four wheels in a direction perpendicular to its axles," the researchers reported Thursday.
What's the point? Nanotrucks, of course.
Eventually the researchers want to build tiny trucks that could carry atoms and molecules around in miniature factories.
The article also has links to the world's smallest motor, robot, refrigerator, and fountain pen. Check it out!
