Abstract:
1. Process for detecting one or more chemical or biological species within a liquid, wherein the species either reacts in a redox reaction or directly or indirectly generates a molecule that reacts in a redox reaction, wherein current generated by said redox reaction is detected at the surface of at least one electrode, comprising the following steps: positioning a quantity of the species or molecule, which quantity varies over time, on, at or in the proximity of the at least one electrode within a period t multiple switching of the at least one electrode back and forth during the period t detecting the current generated by the repeated reduction and oxidation of the species/molecule in the at least one electrode over the period t measuring the current flow in the at least one electrode during the time interval t plotting the current flow during the time interval t adding up the absolute values of the current signals, whereby a curve is obtained, which indicates the absolute value of the current flow over time, characterized in that it is observed for the qualitative detection of the species whether the curve after stopping the liquid is higher in the range t
