Abstract

This paper describes the detection of an inhibitor of acetylcholine esterase with a new device. Detection of conductivity changes in a microcavity by the action of the enzyme was measured with the ion responding impedance sensor (IRIS). A model pesticide, paraoxone, was studied with the IRIS. The detection limit for paraoxone with the device was 10-8 M (3 ppb).
