الملخص:A disposable amperometric biosensor for commercial use to detect hydrogenperoxide has been developed. The sensor is based on screen-printed carbon paste electrodesmodified by electropolymerization of pyrrole with horseradish peroxidase (HRP) entrapped.The facture techniques of fabricating the enzyme electrodes are suitable for mass productionand quality control. The biosensor shows a linear amperometric response to H2O2 from 0.1to 2.0 mM, with a sensitivity of 33.24 μA mM-1 cm-2. Different operational parameters ofelectropolymerization are evaluated and optimized.
