Catechol-modified-chitosan films are redox-active and can exist in oxidized or reduced states. These films can be reductively charged either electrochemically or enzymatically by mediated redox-cycling reactions. Oxidative-discharging is achieved by electrochemical mediator redox-cycling or by donating electrons to O2 to generate a substrate (H2O2) for subsequent enzymatic (peroxidase) reactions. Thus, these films can inter-convert electrochemical and biochemical inputs/outputs.
