Two-electrode systems were fabricated by screen-printing, including one working graphite electrode and a pseudo Ag/AgCl electrode. The screen-printed electrodes were used as amperometric detectors in biosensors based on NAD+-dependent dehydrogenases or genetically modified acetylcholinesterass. Three configuration are presented: (i) the enzyme and the cofactor are deposited on the electrode surface without immobilisation; (ii) the enzyme is deposited on the electrode surface together with the immobilisation agent; (iii) the enzyme is deposited on the electrode surface, while the immobilisation agent is included in the graphite electrode.
