Petty (Center for Molecular and Nanoscale Electronics, Durham University, UK) provides an introduction to the interdisciplinary subject of molecular electronics
, with detailed examples of applications.
One of the objectives in molecular electronics
is to build linkers and channels that enable important charge transfer processes to take place across long distances between donor and acceptor sites.
Durham is the location for world-class work in photonics, cell biology, molecular electronics
and microsystems ( for which a new clean room was opened by Sir David King, the Government's chief scientific adviser, in October.
These include molecular electronics
where the nanotubes are used as both wiring and, with modification of the nanotube itself, electronic devices.
However, wiring them together and connecting them to larger devices remain "big issues to be solved in order to advance this field" of molecular electronics
, Rosei says.
Some specific subjects include peptide-based computation, molecular electronics
and protein-based optical computing, and enzyme logic digital biosensors for biomedical applications.
the relationship between current and voltage and the origins of electrical resistance); the role of geometry, size, and microstructure in determining resistance at the nanoscale; techniques for probing the electrical properties of structures and devices at the nanoscale; heating and electromigration in nanowires; and the emerging field of molecular electronics

"These are very narrow, very long wires that can be designed into patterns for molecular electronics
or biosensors," says Lee.
Moving up the length scale, Antonella Badia, MCIC, is focused on ultrathin organic films of self-assembled alkyl-thiol monolayers or phase-separated lipid mono- and bilayers and seeks to achieve complex lateral structure on surfaces that can serve as nanoscale templates for molecular electronics
Sir David King, the Government's chief scientific adviser, made his comments when he officially opened the university's new pounds 500,000 Molecular Electronics
and Microsystems clean room.
The fabrication of this nanotube transistor represents "a new, important step towards molecular electronics
," Dekker says.
