Man Could Walk on Walls Using New Gecko Glue

Geckos have the gravity-defying ability to climb smooth walls and hang from the ceiling by a single toe, thanks to the intermolecular van der Waals forces that give the microscopic hairs on their toes incredible adhesive properties. Scientists, fascinated with the idea of creating a super-sticky dry glue that can easily be lifted and reapplied, have studied the gecko’s spatula-tipped setae and developed an adhesive based on nature’s design. The newest version, made from carbon nanotubes that mimic the lizard’s microhairs, is 10 times stickier than a gecko’s feet; a mere 1-in (2.5-cm) square can support the weight of a …
