The two front feet of a tokay gecko can withstand 20.1 N of force parallel to the surface with 227 mm 2 of pad area, [4] a force as much as 40 times the gecko's weight. . Scientists have been investigating the secret of this extraordinary adhesion ever since the 19th century, and at least seven possible mechanisms for gecko adhesion have been discussed over the past 17
Nano tape, also called gecko tape is a synthetic adhesive tape consisting of arrays of carbon nanotubes transferred onto a backing material of flexible polymer tape. These arrays are called synthetic setae and mimic the nanostructures found on the toes of a gecko ; this is an example of biomimicry .
In 2007, researchers from the University of Akron and Rensselaer Polytechnic Institute announced they had developed a form of flexible, reusable gecko tape using carbon nanotubes to create microscopic synthetic setae and spatulae capable of supporting a shear stress of 32 N/cm 2, which is four times the strength of a gecko's foot.
The micrometer-scale setae branch into nanometer-scale projections called spatulae. [6] A Tokay gecko's two front feet can sustain 20.1 N of force parallel to the surface using approximately 14,400 setae per mm 2. This equates to ~ 6.2 pN per seta, but does not sufficiently account for the overall stickiness behavior shown by the foot pads. [7]

The interactions between the gecko's feet and the climbing surface are stronger than simple surface area effects. On its feet, the gecko has many microscopic hairs, or setae (singular seta), that increase the Van der Waals forces - the distance-dependent attraction between atoms or molecules - between its feet and the surface.
Put the copy in folder C:\wiki (another drive letter is also possible, but wiki should not be a sub-folder) and do not use any file name extension. This way the links work. This way the links work. One inconvenient aspect is that you cannot open a file in a folder listing by clicking on it, because of the lack of a file name extension.
