From environmental monitoring to point-of-care biofluid analysis, rapid ion determination
requires robust analytical tools. In recent years, driven by the development of materials …

Wearable chemical sensors have recently received great attention, especially on monitoring
ion concentration in sweat. However, challenges still remain, such as the nonnegligible …

A simple, instrument-free method to control the standard potential (E°) of potentiometric solid-
contact ion-selective electrodes (SC-ISE) is described. In this method, the electrode potential …

By its nature, a traditional potentiometric cell composed of an Ag/AgCl-based reference
electrode and a solid-contact indicating electrode is not symmetric. This results in …

This study used a polyurethane (PU)-based ion selective electrode (ISE) immobilized with di-
(2-ethyl hexyl) phosphoric acid (D2EHPA) to detect and quantify Pb 2+ ions at low …

Different causes can trigger imbalances on homeostatic mechanisms between intracellular
and extracellular compartments resulting in abnormal blood potassium concentrations (hypo …

Solid contact polymeric ion-selective electrodes (SC-ISEs) have been fabricated using
microporous carbon (μPC) as the ion-to-electron transducer, loaded with a liquid membrane …

Using a standardized miniature format ion selective electrode, five different carbon based
solid contact materials, including a novel commercially available graphene oxide assisted …

Here we present for the first time the use of graphene oxide nanoparticles as fixed-charge
carriers for the development of membrane-based cation selective ion-selective electrodes …

Potentiometric sensors are very attractive tools for chemical analysis because of their
simplicity, low power consumption and low cost. They are extensively used in clinical …
