Orbital interaction mechanisms of conductance enhancement and reactification by dithiocarboxylate anchoring group
Article Abstract:
The electron transport properties of dithiocarboxylate terminated molecular junctions are investigated computationally. The findings show that the peaks in the transmission spectra of 4'-thiolato-biphenyl-4-dithiocarboxylate junction respond differently to the applied voltage and depending on the origin of a transmission resonance in the orbital interaction picture, its energy could be shifted along with the chemical potential of the electrode to which the molecule is more strongly or more weakly coupled.

A new strategy for ratiometric fluorescence detection of transition metal ions
Article Abstract:
A new design strategy for ratiometric fluorescence signaling of transition metal ions, involving both photoinduced electron transfer and resonance energy transfer mechanisms was tested on a model system comprising dual fluorophores. The results showed that the design strategy was effective for detection of meal ions and suggests that it would be possible to develop sensor systems for practical usage based on this design.

Base sequence effects on transport in DNA
Article Abstract:
The calculations of the polaron model based on solvation in accounting for the width of a hole polaron on an all-adenine (A) sequence on DNA is extended to other sequences. The properties of electron polarons in DNA and the implications of the results for the mechanism of transport of excess electrons and holes are discussed.
