A Molecular Gearing System. [1]

Technomimetics are molecular systems that can mimic man-made devices. The term was first introduced in 1997. [1] The current set of technomimetic molecules [2] includes motors, [3] rotors, [4] gears, [5] gyroscopes, [6] tweezers, [7] and other molecular devices. Technomimetics can be considered as the essential components of molecular machines and have the primary use in molecular nanotechnology.
