Abstract

Amperometric biosensors, e.g. for determining blood glucose, employ electrodes, preferably of graphite or glassy carbon, which have been modified by electrochemical deposition of a Prussian blue - type coating. Such electrodes are capable of amperometric detection of hydrogen peroxide, largely unaffected by potential interferents including ascorbate and paracetamol. A hydrogen peroxide-generating enzyme may be immobilised on the electrode or otherwise coupled to it so that the system becomes a biosensor.
