The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Applications of nanomaterials in potentiometric sensors (2013, methodology): “In the past few years, ISEs have made great progress in improving the lower limit of detection (LOD), exploiting new membrane materials, proposing new sensing concepts and developing deeper theoretical research about potentiometric responses [2].”
Applications of conducting polymer composites to electrochemical sensors: A review (2017, background): “The lowest detection limits of potentiometric devices are currently often realized with ion-selective electrodes (ISE) [77,83].”
Microbial biosensors: a review. (2011, methodology): “The transducer employed in the potentiometric technique s usually a gas-sensing electrode or an ion-selective electrode Bobacka et al., 2008; Lei et al., 2006a).”
Rational design of all-solid-state ion-selective electrodes and reference electrodes (2016, background): “Therefore, POT films have a relatively low redox capacitance and electronic conductivity [5], and ion-to-electron transduction at their interfaces occurs mainly through the electrical double layer that forms at the solid contact/membrane boundary, as discussed in Section 2.”
