Abstract

The present project aims the development of an ultracompact three-dimensional electrochemical cell combining materials with distinct natures and dimensionalities through microfabrication processes. In addition, this cell will be characterized by electrochemical measurements of cyclic voltammetry and impedance spectroscopy. The proposed device will be manufactured having electrode's configuration like a conventional electrochemical cell. Its structure will be composed of three electrodes: reference electrode, working electrode and counter electrode. Such devices will be fabricated and characterized from two-dimensional (2D) structures, where it is possible to limit the region to be analyzed. The characterizations will also be performed on three-dimensional (3D) structures, where the region to be analyzed is limited by the tubular shape of the system. The development of electrochemical cells composed of three electrodes and based on nanomembranes (NMs) is an innovative device, without previous reports in literature. Defined as a nanomembrane-based electrochemical cell (NanoMEC), the development represents a challenge when considering the combination of materials with different natures and dimensionalities through microfabrication processes. Finally, as a proof-of-concept working electrode will be individually modified with polydopamine (PDA) in order to allow the adhesion of biomolecules to verify sensory activity of the fabricated devices.
