Evaluate the Performance of Ethanol biosensor with Different Electrodes Coated with Alcohol Oxidase in Food

Ethanol biosensor was used to measure low values of ethanol with precision and high selectivity by amperometric method in different industrial fields. In this paper, the performance of biosensor has been evaluated by measuringthe current rate transferred in different concentrations of ethanol and different Working Electrodes (W.E). The obtained results of comprise Pt-PEDOT, Pt-PVF, SCP-C, SCP-Pt electrodes coated with alcohol oxidase as the anode in amperometric biosensor were indicated that SCP-C electrode has high efficiency in ethanol concentrations less than ٠.٦ mM.
