This volume concentrates on the measurement, synthesis, assembly and manipulation of molecular wires and nanostructures. It incorporates the assembly and use of molecules into nanostructures (nanoparticles, quantum dots, catenanes, conducting oligomers, DNA) for electronic switching. Work is presented in the following areas: single molecule conductance; biomolecular conductors; electronic nanostructures; the theory of charge transport in molecular wires and nanostructures; conjugated electronic oligomers; nanogap devices. Faraday Discussions document a long-established series of Faraday Discussion meetings which provide a unique international forum for the exchange of views and newly acquired results in developing areas of physical chemistry, biophysical chemistry and chemical physics. The papers presented are published in the Faraday Discussion volume together with a record of the discussion contributions made at the meeting. Faraday Discussions therefore provide an important record of current international knowledge and views in the field concerned.
