Ion-selective Electrodes in the Study of Cholinesterases

This review is devoted to the application of various types of ion-selective electrodes in the study of the activities and catalytic properties of cholinesterases and also in chemical analysis with participation of these enzymes. Studies using a membrane "substrate" electrode, a glass pH electrode, an oxidation-reduction platinum electrode, and a polycrystalline electrode based on silver sulphide are considered. Investigations using enzyme electrodes based on immobilised cholinesterases are also described. The advantages and disadvantages of individual methods employing different types of ion-selective electrodes are discussed.
