From gecko feet, lesson in nanotube transfer
RICE (US)—Geckos seem to defy gravity by sticking to a surface no matter how smooth it appears to be—all thanks to the electrical attraction between millions of microscopic hairs on the gecko’s feet and the surface. The same concept is allowing researchers to transfer forests of strongly aligned, single-walled carbon nanotubes from one surface to another in a matter of minutes. (more…)
