The components of the machine assemble by self - organisation Of course, unlike
macroscopic machines, the nanomachine was not assembled with a welding torch or wrench.
When driving a car, the clutch mechanically carries the torque produced by the engine to the chassis of the vehicle — a coupling that has long been tested and optimized in such
macroscopic machines, giving us highly efficient engines.
The innovative aspect of this activity was the notion that the concept of
macroscopic devices could be extended to the molecular level, and that it was possible to design supramolecular systems that, upon stimulation with external energy stimuli such as UV / Visible light, are capable of performing a variety of specific functions: (i) systems for information processing (e.g., wires, switches, antennas, plug / socket systems, extension cables, memories, logic gates, encoder / decoder, rudimentary neuron - like systems), (ii) devices that when powered by chemical energy or electrochemical energy or by light exhibit
machine - like behavior (e.g., piston / cylinder systems, shuttles, lifts, rotary rings, dendritic photo - switchable boxes), and (iii) components for artificial photosynthetic systems.
