Abstract

We report a new, sensitive detection method for the measurement of analytes based on the combination of conducting polymer technology and redox enzyme electrochemistry. This method provides a simple measurement method potentially enabling point of care testing on disposable electrodes in under 60 s. The measurement does not require a reference or counter electrode and the analytical signal is recorded by an ammeter measuring milliampere currents through a polymer transistor. Even at very low analyte concentration, the signal is not subject to significant noise.
