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.
