New Nano-Brushes Keep the Tiny Tidy

Abstract:
Even at the nano-scale — where machines and materials can be the size of atoms and molecules — there are messes to sweep, walls to paint, tubes to unclog, and electronics to power. And now there's a way to make the tiniest of brushes to do these chores.

To work at the nano-scale, researchers realized that a different kind of material was needed. "It dawned on us that [carbon] nanotubes would make excellent bristle material," Pulickel Ajayan, a professor of materials science and engineering at the Rensselaer Polytechnic Institute (RPI)
