TLDR
A multi-pulse procedure that allows one to perform a second excitation pulse at the same excitation potential after exhaustive ion transfer voltammetry of calcium has taken place is introduced, supporting that the procedure renders the readout principle more robust.About:

Opportunities and challenges of using ion-selective electrodes in environmental monitoring and wearable sensors
Claudio Zuliani,Dermot Diamond +1 more
TL;DR: Great opportunities exist for ion-selective electrodes in the fields of environmental monitoring and of wearable applications for example as the sensing part in wireless networks and their combination as disposable sensing platform may offer the best solution to eliminate issues commonly experienced with ISEs.

Instrument-free control of the standard potential of potentiometric solid-contact ion-selective electrodes by short-circuiting with a conventional reference electrode.
Ulriika Vanamo,Johan Bobacka +1 more
TL;DR: The short-circuiting method is an important step toward calibration-free potentiometric analysis and is studied experimentally for SC-ISEs where the conducting polymer poly(3,4-ethylenedioxythiophene) doped with the bulky anion poly(sodium 4-styrenesulfonate), PEDOT(PSS), is used as the solid contact.

Enhancing ion-selective polymeric membrane electrodes by instrumental control
TL;DR: In this article, the authors highlight a recent important direction to place ion-selective electrodes based on polymeric sensing materials under dynamic electrochemistry control, which allows one to design sensors with a range of improved characteristics.
Journal ArticleDOI
Advances and trends in ionophore-based chemical sensors
TL;DR: The role of the heterogeneity of the sensor/sample systems is emphasized, and it is shown that due to this heterogeneity such sensors respond to the analyte activities rather than to concentrations as mentioned in this paper.

Voltammetry of the phase transfer of polypeptide protamines across polarized liquid/liquid interfaces.
TL;DR: It was shown that the shape of the voltammograms is limited by the interfacial transfer of protamines, and ITIES will serve as a basis of amperometric sensors for biological macromolecules and also as a model for understanding potential-driven membrane transport of these molecules.
