Each of these hairs, known as setae, finishes in hundreds of even finer spatula-shaped split-ends. The hairs, known as setae, generate a multitude of weak attractions between molecules on the two surfaces that add up to a secure foothold. Geckos are famous for having grippy feet that allow them to scale vertical surfaces with ease. As the group of runners stumbleed toward the finish line, their exhaustion was apparent.

The connection breaks when the gecko shifts its foot enough to change the angle between the hairs and the surface. Unit Operations of Chemical Engineering (Warren L. McCabe; Julian C.

Now researchers have discovered how a balance of forces acting on the gecko and the angle of its toe hairs contribute to the creature's sticking success. The best way to prevent this foot problem is to stay moisturized. 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.
