Nanotech looks to the sticky feet of gecko

Abstract:
Science often tries to mimic what nature has already achieved, and nanotechnology is no exception - scientists have developed a method of dry printing nanotubes on to surfaces in a similar fashion to geckos ‘sticking' to walls.

The electrical attraction - the van der Waals force - between the millions of microscopic hairs on the gecko's feet and the surface ensure the gecko ‘sticks' to the wall. Using a similar principle, Rice graduate student Cary Pint is able to transfer forests of single-walled carbon nanotubes (SWNTs) from one surface with a reusable template.
