Amperometric biosensing of ethanol based on integration of alcohol dehydrogenase with a Pt/PPy–PVS/MB electrode
The results showed that 95.7% of the response current was retained after 17 activity assays. The ethanol biosensor gave perfect reproducible finding with 4.6% relative standard deviation. The prepared biosensor retained 55.8% of initial activity after 24 days when stored in 0.1 M phosphate buffer solution at 4 ◦ C. Effects of the several possible interfering substances such as ascorbic acid, citric acid, and methanol on the ethanol biosensor were investigated and the developed biosensor was test
