NIST's synchrotron microscope is well-suited to take a closer look at the molecular structure because it is able to not just identify molecules on the surface of three-dimensional objects, but also to reveal precisely where they are located and how they are oriented. Furthermore, the setae and spatulae are composed of keratin protein, much like the proteins in human hair and fingernails. Gamble showed that geckos probably acquired their adhesive toes in at least eleven separate events, and lost them again on nine occasions.

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 secret to that directionality was theangle and shape of the fabricated half-cylinder fibers in the silicon-based adhesive.
