We provide the first direct experimental evidence for dry adhesion of gecko setae by van der Waals forces, and reject the use of mechanisms relying on high. Fig. 1. Force of gecko setae on highly polarizable surfaces versus for surface hydrophobicity. (A) Wet adhesion prediction. (B) van der Waals prediction. Functionally, the properties of gecko setae are as extraordinary as their structure: .. the first direct evidence that intermolecular forces are responsible for hypothesis that van der Waals forces are sufficient for gecko adhesion by reanalyzing.

Evidence for van der Waals adhesion in gecko setae. A van der Waals mechanism implies that the remarkable adhesive properties of gecko setae are merely a result of the size and shape of the tips, and are not strongly affected by surface chemistry.
