EVIDENCE FOR VAN DER WAALS ADHESION IN GECKO SETAE PDF

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.

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 surface polarity, including capillary adhesion.

Liang and Anne M. NiewiarowskiAli Dhinojwala Integrative and comparative biology This paper has highly influenced 17 other papers. 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. D Results from single seta attaching to highly polarizable MEMS cantilevers differing in hydrophobicity.

The mechanism of dry adhesion in the millions of setae on the toes of geckos has been the focus of scientific study for over a century. Adhesion of a single isolated gecko seta was equally effective on the hydrophobic and hydrophilic surfaces of a microelectro-mechanical systems force sensor.
