a linear correlation has been observed between the log (glucose concentration) and measured potentials at bare pt-and at enzyme/pt-indicating electrodes. a comparison study of five different methods of electrode pretreatment was undertaken to evaluate the nernstian behavior of the sensors. the potentiostatically controlled double-layer and the platinic chloride-treated electrodes exhibited the greatest differences in potentiometric response between the metal and the enzyme/metal electrodes. sensors fabricated with flame-oxidized and with potentiostatic-oxidized or reduced pt surfaces demonstrated little difference in nernstian response between the two types of indicating electrodes.
