More than a decade of research and engineering has culminated in gecko tape: a re-useable adhesive that has a structured surface similar to that of geckos and that outperforms the usual sticky tape. Scientists have recreated geckolike adhesion using silicones, plastics, carbon nanotubes, and other materialsbut they've run into a scaling problem: The stickiness diminishes when the size of the adhesive exceeds a few square centimeters, severely limiting its practical applications. Each hair branches off into even smaller fibers called spatulae. It has long been known that at microscopic size scales, the so-called van der Waals forcesthe attractive and repulsive forces between two dipole moleculesbecome significant.
