Each seta ends in an array of nanostructures, called spatulae,that function as a dry adhesive. Since then, they have spread across the world, and many of them have climbed up it.

Please make a tax-deductible gift today. 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. The team then connected the tiles to springs with tendonlike strings and attached them on an octagonal-shaped plate. 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. 8.
