The amazing climbing ability of geckos has attracted the interest of philosophers and scientists alike for centuries1,2,3. However, only in the past few years2,3 has progress been made in understanding the mechanism behind this ability, which relies on submicrometre keratin hairs covering the soles of geckos. Each hair produces a miniscule force ≈10−7 N (due to van der Waals and/or capillary interactions) but millions of hairs acting together create a formidable adhesion of ≈10 N cm−2… 

Gecko‐Inspired Polymer Adhesives

The discovery of the gecko’s remarkable foot adhesion has provided a riddle for engineers and scientists to solve: how can an adhesive surface be selectively sticky, directional, remain clean, and

Gecko Feet: Natural Hairy Attachment Systems for Smart Adhesion – Mechanism, Modeling and Development of Bio-Inspired Materials

TLDR
A man-made fibrillar structure capable of replicating gecko adhesion has the potential for use in dry, superadhesive tapes that would be of use in a wide range of applications.

Enhanced fabrication and characterization of gecko-inspired mushroom-tipped microfiber adhesives

Geckos exhibit a unique ability to adhere repeatedly and reversibly to a variety of surfaces. Considerable scientific and engineering efforts over the last decade have produced gecko-inspired

Gecko Feet as a Bio Prototype for the Use of Dry Adhesion in Engineering Decisions

The focus of this review is to outline the remarkable ability of the gecko to climb surfaces vertically, at tremendous speed (over 1 m/s) using van der Waals forces (one of nature’s amazing “sticking

Gecko-Inspired, Controlled Adhesion and Its Applications

Gecko feet stick to almost anything, in almost any condition (including underwater and in space), but do not stick unintentionally, do not stick to dirt, and enable the gecko to literally run up the

Advanced gecko-foot-mimetic dry adhesives based on carbon nanotubes.

TLDR
An overview of recent progress in both fundamental and applied frontiers for the development of CNT-based adhesives is presented by summarizing important studies in this exciting field, including the author's own work.

Gecko Feet: Natural Hairy Attachment Systems for Smart Adhesion

TLDR
Modeling of the gecko attachment system as a hierarchical hierarchical spring model spring model has provided insight into the adhesion enhancement generated by this system.

TLDR
Engineered adhesive nanostructures inspired by geckos may become the glue of the future and perhaps the screw of thefuture as well.

Gecko-Inspired Adhesives with Asymmetrically Tilting-Oriented Micropillars.

The anisotropic adhesion behavior of the gecko is closely related to their feet and is comprised of keratinous hairs, setae, where van der Waals forces permit attachment and detachment during

TLDR
The structure that allows gecko lizards and insects to climb vertical and inverted surfaces with ease has been studied extensively and attempts to replicate the structures seen in animals using synthetic materials to create adhesives with similar adhesive characteristics are made.

Adhesive force of a single gecko foot-hair

TLDR
The first direct measurements of single setal force are reported by using a two-dimensional micro-electro-mechanical systems force sensor and a wire as a force gauge and revealed that a seta is ten times more effective at adhesion than predicted from maximal estimates on whole animals.

TLDR
This work provides the first direct experimental evidence for dry adhesion of gecko setae by van der Waals forces, and suggests a possible design principle underlying the repeated, convergent evolution of dry adhesive microstructures in gecko, anoles, skinks, and insects.

Electrically induced structure formation and pattern transfer

TLDR
A simple electrostatic technique is reported that creates and replicates lateral structures in polymer films on a submicrometre length scale, based on the fact that dielectric media experience a force in an electric field gradient.

Experimental Analysis of Adhesion of Chrysolina Polita (Chrysomelidae: Coleoptera) on a Variety of Surfaces

TLDR
Hooks, suction, electrostatic forces and seizure are largely discredited, and molecular adhesion between the setae and the substratum, and possibly the cohesive forces and surface tension of a thin fluid layer, are confirmed as the most likely modes of adhesion on smooth surfaces in C. polita and most beetles.
