Abstract

The electrochemical properties of thin-film gold electrodes for the purpose of biosensors, implantable sensors and microsensors have been studied by Electrochemical Impedance Spectroscopy (EIS) and cyclic voltammetry(CV). Thin-film gold was deposited on to flexible PTFE substrates using thermal evaporation techniques. Ferrocene carboxylic acid served as a model of a simple reversible redox reaction. It has been demonstrated that electrodes evaporated on to N-2 plasma modified PTFE is characterised by a low electrode/electrolyte interface impedance and good adhesion and stability at the metal/polymer interface. The electrodes exhibit good reversibility and reproducibility. The possible application of this electrode in the construction of amperometric biosensors was investigated using the glucose oxidase/ferrocene catalytic reaction. It has demonstrated that the thin-film flexible gold electrode is a suitable base transducer for the construction of biosensors, implantable sensors and microsensors.
