“…Self-assembling procedures of conducting or semi-conducting interfaces with electroactive species have become a broadly used methodology for endowing them of new properties that could improve their chemical/electrochemical functionality. [1][2][3][4][5] The resulting modified interfaces have a great number of applications as are the development of new sensors/ biosensors, [6,7] molecular and organic electronics, [8][9][10] and energy storage systems, [11,12] among many others, together with the possibility of exploring in detail fundamental aspects of charge transfer processes as well as the chemical reactivity at electrified interfaces. [13][14][15] In order to adjust optimally the emerging properties of these modified interfaces to a specific purpose, it is necessary to carry out their physicochemical characterization, and specifically, a detailed analysis of their electrochemical functionality.…”
