  • A method based on break-junction measurements to obtain information about the binding configuration of single-molecule junctions is reported. This approach also provides insight on how strain distributes along the molecule.

  • Charge transport in DNA is often described by either tunnelling or hopping, but recent results suggest that coherence is maintained over several bases. Now it is shown that nearest-neighbour interactions play an important role in determining the electronic properties of DNA and that, by utilizing these effects, higher-conductance sequences can be designed.

  • The conductance of a single molecule of 1,4'-benzenedithiol bridged between two gold electrodes increases as it is stretched because the energy of the highest occupied molecular orbital is shifted towards the Fermi energy of the electrodes, leading to a resonant enhancement of the conductance.

  • Coupling charge transfer with molecular protonation processes yields electronic systems that display negative differential conductance, an effect that can be harnessed to implement a wide range of device configurations from logic gates to synaptic behaviour.

  • DNA could find a role in molecular electronics. Here, the authors show that the conductance of DNA can be reversibly changed by an order of magnitude when its conformation is changed from one form to another by controlling its chemical environment.

  • The properties of molecular electronic devices can be tuned by tailoring the structures of the molecules from which they are built. Researchers now show that two closely related molecules — each containing a string of four aryl groups — behave very differently when strung between gold electrodes, with the non-symmetrical structure leading to diode-like behaviour.
