The advantageous scale of the gecko's foot is past the skill of traditional microengineering, yet a staff of nanotechnologists have already made an exceptional preliminary approximation.

The gecko's foot is only one of many examples of this new 'smart' technological know-how. We additionally observe, among different issues, how George de Mestral's brush with the spiny end result of the cocklebur encouraged him to invent Velcro; how the form of leaves commencing from a bud has encouraged the layout of solar-powered satellites; and the parallels among cantilever bridges and the spines of huge mammals resembling the bison.
