Biosensor for in-situ study of reduction-oxidation processes

摘要

The biosensor uses a combination of the resonance of surface plasmons and cyclovoltammetry. A surface plasmon resonance signal and a cyclovoltammogram are produced preferably at the same time from the same sample. Preferred Features: The structure has a triple-electrode configuration, with a working electrode (12), a counter electrode (13) and a reference electrode (14). All the electrodes are contained in a measurement cell. The sensor surface for the surface plasmon resonance also acts as the working electrode for cyclovoltammetric measurement. The measurement cell has an inlet and outlet for an inert gas.
