A prussian‐blue thin film assembled on an Au electrode yields an optoelectronic three‐state switching system for the photonic transduction of electrical signals, and a sensing device for the electrocatalyzed oxidation of NADH, using surface plasmon resonance (SPR) spectroscopy. The SPR spectra measured for the modified Au surface are shown for different potentials and the generation of the different redox states of the prussian‐blue film: −0.2 V=fully reduced, 0.3 V=semi‐oxidized, 0.9 V=fully oxidized.
