TTF-Modified Biosensors for Hydrogen Peroxide

TTF-Modified Biosensors for Hydrogen Peroxide

Amperometric biosensors for hydrogen peroxide were produced, based on TTF-modified graphite disc electrodes, incorporating immobilised peroxidase. At the optimum operating potential (−200 mV vs. calomel electrode), a linear response to hydrogen peroxide was obtained in the range 0-2 mM (Km value = 1...

Zusammenfassung:Amperometric biosensors for hydrogen peroxide were produced, based on TTF-modified graphite disc electrodes, incorporating immobilised peroxidase. At the optimum operating potential (−200 mV vs. calomel electrode), a linear response to hydrogen peroxide was obtained in the range 0-2 mM (Km value = 1.98 mM). Low sensitivity to pH fluctuations and good stability at room temperature were exhibited.
