Fabrication and Characterisation of Membrane‐Based Gold Electrodes

This work presents a versatile, membrane based electrochemical sensor with thin film electrodes fabricated through E‐beam evaporation directly on porous materials (membranes). Here, the fabrication of the electrodes is described along with possible methods for integration in fluidic systems and characterisation of the electrodes through cyclic voltammetry (CV). The continued porous nature of the membranes after metal deposition is documented and its robustness and stability is investigated. Furthermore, amperometric sensing of dopamine is demonstrated as a proof of concept to validate the usability of the membrane sensor.
