Abstract Electrochemical sensors that work with molecular switching mechanisms arepromising for the detection of pollutants and diseases. Molecular switching revolvesnanoscale charge transfer phenomena and mesoscopic scale transports and,therefore, provides a more complete understanding of these systems; this can beachieved by studying individual processes and allows integrating them to a suitablephysical model. In this work we propose the study of molecular switching devicesthrough the following steps: fabrication of redox active electrodes modified withpeptide monolayers; attachment of redox active sites and gold nanoparticles to theelectrodes via molecular links; in-depth investigation of structural and electrochemicalcharacteristics with and in-operando characterization of the nanoscale phenomenawith scanning probe techniques in an electrochemical environment. We believe thatthe combination of the electrochemical and in-operando results will lead to the fullunderstanding and, therefore, optimization of devices for practical applications. | |
