TL;DR: A general methodology to calculate the individual sensitivity and the cross-sensitivities of potentiometric sensor devices with an arbitrary number of non-interacting receptors binding to ionic species or analytes in the electrolyte is proposed.

TL;DR: This work reports systematic DC, transient, and noise characterizations and models of a back-end of line (BEOL)-modified foundry-made ISFET used as pH sensor to determine the sensor sensitivity and resolution to pH changes and to calibrate numerical and lumped element models, capable of supporting the interpretation of the experimental findings.

TL;DR: In this article, the spectral density of the surface charge fluctuations, so-called chemical noise, from a generic set of reactions at the sensing surface of potentiometric sensors such as, for instance, Ion-Sensitive Field Effect Transistors (ISFETs), is derived.

TL;DR: In this paper, a steady state model for ion selective membranes (ISM) as selectivity element in potentiometric sensors is proposed, coupled with distributed chemical reactions between ionophores and two types of competing ions.

TL;DR: In this article, a model of arbitrary chemical reactions at the interface between a solid and an electrolyte, aimed at computing the interface charge build-up and surface potential shift of ion-sensitive FETs in the presence of interfering ions is presented.
