Molecular devices and machines

The bottom-up design, construction, and operation of devices and machines on the molecular scale is a topic of great interest in nanoscience and a fascinating challenge for nanotechnology. Species made of interlocked molecular components are most attractive candidates for these purposes. In recent times, the evolution of the structural and functional design of such systems has led to the construction and operation of complex molecular devices and machines that, in some cases, are able to perform specific tasks.
