Carbon Nanotubes as an Adhesive
Scientists have come up with a way to transfer forests of strongly aligned, single-walled carbon nanotubes from one surface to another, on any surface, in a matter of minutes. The template used to grow the nanotubes, with its catalyst particles still intact, can be used repeatedly to grow more nanotubes, almost like inking a rubber stamp. Inspired by how a gecko sticks to the smoothest of surfaces via strong van der Waals force between its millions of hairs, the process could revolutionize microelectronics.
