A lock ( 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. Actress Michelle Yeoh shows off her feet at the Volver premiere at the Palais des Festivals during the 59th International Cannes Film Festival on May 19, 2006, in Cannes, France (Credit: Featureflash Photo Agency / Shutterstock). So some hairs max out their stickiness, whereas others are underutilized or not attached to the surface at all. Those toes that maintained contact with the surface were able to shift orientation and better distribute the load. The scaling problem stems in part from the fact that loads don't distribute uniformly across large areas of adhesives, report researchers from Stanford University in Palo Alto, California, in a study published online today in the Journal of the Royal Society Interface.

"Nature has had more time than we have had. They have no suction cups, hooks or glue on their feet, so how do they do it? The synthetic hairs -- one ten-thousandth the width of a human hair -- are made of highly flexible carbon cylinders, or nanotubes, embedded in a plastic base like bristles in a hairbrush. Jaye et al. The study may also be useful to the many people who are trying to duplicate the geckos powers, by mimicking their feet using man-made materials. As a result, the tiny hairs touch so much surface area so closely that weak forces of attraction between molecules in the hairs and in whatever surface the animal is walking on add up and become sufficient to let the gecko hang on. ", Gravity-Defying Geckos Teach Scientists a Lesson, https://www.nytimes.com/2005/08/30/science/gravitydefying-geckos-teach-scientists-a-lesson.html.
