Abstract: | In this study, a novel conductive polymer comprising biosensor based on poly-2,2 '-(9,9-dioctyl-9 h-fluorene-2,7-diyl)bistiophene (Poly(BT)) and acetylcholinesterase (AChE) was reported for the determination of paraoxon. This practical biosensor allowed to catalyze electrochemical oxidation of acetylthiocholine (+0.6 V vs. Ag reference). The detection range for acetylcholine chloride (AThCl) with Poly(BT)/AChE was found to be 0.025-4 mM. In pesticide analysis, wide linear ranges from 0.5 to 1 mu g/L and 1 to 14 mu g/L, and a low detection limit of 0.033 mu g/L were estimated. Under optimum operating conditions, the developed biosensor was used for pesticide detection in milk and tap water samples, effectively. |
