An amperometric biosensor based on acetylcholinesterase was constructed by simple adsorption of the enzyme on screen-printed electrodes (SPEs). This sensor was used to detect the inhibitory effects of organophosphorus and carbamate insecticides on acetylcholinesterase, and more particularly of chlorpyrifos ethyl oxon (CP-o). We demonstrate that enzyme adsorption on SPEs allows to obtain stable sensors that present good characteristics and are as efficient as other screen-printed biosensors based on covalent binding or entrapment of acetylcholinesterase (AChE).
