Reybier K, Zairi S, Jaffrezic-Renault N, Fahys B: The use of polyethyleneimine for fabrication of potentiometric cholinesterase biosensors. Talanta. 2002 Apr 8;56(6):1015-20. Potentiometric biosensors based on butyrylcholinesterase are developed by co-reticulation of the enzyme with glutaraldehyde on an electropolymerized polyethyleneimine film at the electrode surface. The BuChE-electrode was tested as biochemical sensor for detection of an organophosphorus pesticide, trichlorfon in liquid, the detection being based on the enzyme inhibition. The enzyme electrode showed a detection limit for trichlorfon below 10 (-7) M. |
