Refers to biomimetic products modeled on the adhesion properties of the underside of gecko toes which has layered ridges with very fine keratinous hairs (setae) that provide intimate contact with virtually any surface. Research has been carried out to study the degrees of adhesion provided by different shapes and arrangements of nanofiber arrays and to mimic the setae in synthetic materials. Gecko adhesion is dry and mechanically activated, which offers a solution for some problems, such as solvent damage and inadequate reversibility, with existing museum adhesives.
