Enhancing ion-selective polymeric membrane electrodes by instrumental control

Published in Trends in Analytical Chemistry. 2014, vol. 53, p. 98-105
Abstract This review aims to highlight a recent important direction to place ion-selective electrodes based on polymeric sensing materials under dynamic electrochemistry control. This allows one to design sensors with a range of improved characteristics. This review also showcases developments to achieve calibration-free ion-sensing strategies by using thin layer coulometry at ion-selective membranes. Finally, strategies to fabricate electrochemically-addressable ion-selective thin membrane layers are discussed, especially in view of realizing stripping ion-transfer voltammetric sensors.
