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 componentsNanotechnologyMolecular electronicsNanotechnology.Molecular electronics.540547/.5620/.5Balzani Vincenzo1936-321150Venturi M(Margherita)321151Credi A(Alberto)301786MiAaPQMiAaPQMiAaPQBOOK996204216103316Molecular Devices and Machines742424UNISA
