Along with colleagues in Oregon, Denmark, and Germany, researchers at the National Institute of Standards and Technology (NIST) took a closer look at those structures using high-energy synchrotron, revealing that they are coated with an ultra-thin layer of lipid molecules in an upright orientation, according to a recent paper published in the journal Biology Letters. Pull a foot in one direction and the gecko toes will grab onto a surface.

In 2013, for instance, scientists at the University of California, Santa Barbara, designed a reusable dry adhesive inspired by the gecko's feet that easily stuck to smooth surfaces, adhering strongly when pushed forward and sliding off when pulled backward. To transform spinules into setae, its a simple matter of lengthening them and flaring their tips out into split ends. The earliest days of the dinosaurs found the gecko amongst the animals that emerged. Right: A close-up view of an individual spatula.
