Monitoring interfacial bioelectrochemistry using a FRET switch

Article Abstract:

A demonstration that by covalently tethering an appropriate dye to the copper protein azurin a highly oxidation-state-sensitive fluorescence resonance energy transfer process could be established which enables redox switching to be optically monitored at protein levels down to the zeptomolar limit is presented. The surface-potential-induced cycling of emission enables the redox potential of clusters of a few hundred molecules to be determined.

Dynamic diffuse double-layer model for the electrochemistry of nanometer-sized electrodes

Article Abstract:

A dynamic diffuse double-layer model is developed for describing the electrode/electrolyte interface bearing a redox reaction. The model consists of a dynamic potential distribution equation containing the influence of current and a voltammetric equation containing the influence of the double-layer.
