Electrochemical and Piezoelectric Enantioselective Sensors and Biosensors

Abstract

Enantioselectivity in chemical and biochemical sensing probes can be obtained by the use of enantioselective binding or by enantioselective biocatalysis. The enantioseletive discrimination in ion‐selective electrodes can be achieved with the use of appropriate ionophore in plasticized membrane in measuring cell or on the surface of electrode, with the use of a suitable enzyme in biosensor, antibody in immunosensor, or molecularly imprinted polymer for modification of active surface of amperometric or voltammetric sensor. This review, based on 77 literature references mostly from 1992 to 2004, reports developments of such sensors for potentiometric, amperometric, and mass‐detecting devices involving quartz crystal microbalances.
