Emerging functional materials in solid-contact potentiometric sensing, a field full of vitality

Abstract

Potentiometric sensing is used to quantify the analyte via potential readouts between the working and reference electrodes. All-solid-state potentiometric sensors are drawing significant attention, with a variety of functional materials being utilized as the solid contacts to realize the ion-to-electron transduction. Some emerging materials and novel modes of potentiometric sensing have come into play in recent research endeavors.
