Evidence for van der Waals adhesion in gecko setae.

Immunolocalization of specific keratin associated beta-proteins beta-keratins in the adhesive setae of Gekko gecko. The toes of live Tokay geckos were highly hydrophobic, and adhered equally well to strongly hydrophobic and strongly hydrophilic, polarizable surfaces. Kenny and Ronald S.
