Researchers say they have developed an adhesive that can stick stronger than the toes of geckos. The little lizard can dash up walls and hang from the ceiling by a single toe, thanks to microscopic hairs on the soles of its feet that latch onto nooks and crannies on surfaces.
A team of materials scientists (from the University of Dayton, Wright-Patterson Air Force Base, the University of Akron, and the Georgia Institute of Technology) report in Science today that they used carbon nanotubes (tiny tubes of carbon about 1/50,000th the width of a human hair) to model the shape of gecko microhairs (each hair is straight with a curly top).
