• Sommario/riassunto: The miniaturization of bulky devices and machines is a process that confronts us on a daily basis. However, nanoscale machines with varied and novel characteristics may also result from the enlargement of extremely small building blocks, namely individual molecules. This bottom-up approach to nanotechnology is already being pursued in information technology, with many other branches about to follow.Written by a team of experienced authors headed by Vincenzo Balzani, one of the pioneers in the development of molecular machinesCovers such diverse aspects as sensors, memory components
