1. Electrochemical sensors

1.1 Surface structuring at different scales

Bioelectrochemical sensors are generally based on the immobilization of a biological element (enzyme, DNA strand, antibody, microorganism, etc.) on an electrode, which acts as a transducer . The molecular recognition event is thus translated into a change in current, potential or impedance. In the first case, the miniaturization of an electrode is...
