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. But therein lies the beauty of the system: It could easily adapt to different situations, just by replacing the adhesive tiles with other types of geckolike adhesivesfor example, adhesives that self-clean like real gecko hairs. Faced with sheer surfaces, they have evolved subtle variants on the same adaptation, time and again.

This can help biomimetic engineers know what to do next., You can imagine gecko boots that dont slip on wet surfaces, or gecko gloves for holding tools that are wet, said NIST physicist and co-author Dan Fischer. Polytetrafluoroethylene (PTFE), more commonly known as Teflon, is a plastic material often used to coat several different cookware and utensils to make them non-stick [4]. Now they have a clearer picture of the molecular structures that give the animal its grip.
