Abstract This work reports for the first efforts in establishing the operational conditions necessary for converting a Direct Glucose Fuel Cell (DGFC) into a Molecularly Imprinted Polymer (MIP) based electrochemical autonomous biosensor. Electrochemical studies were performed in a typical three electrodes system besides Anion and Proton Exchange Membrane (AEM and PEM) fuel cells, applying voltammetric and Electrochemical Impedance Spectroscopy (EIS) techniques. Promissory results were obtained for the PEM-DGFC that revealed potential to be converted into a biosensor. Further studies are ongoing by resourcing to MIP technology to convert the PEM-DGFC into an electrochemical sensor for cancer biomarkers.
