✦ Synopsis

This article reviews recent advances in the ®eld of potentiometric solvent polymeric membrane electrodes. These sensors have found widespread applications in a variety of ®elds, especially in the area of clinical diagnostics. Emphasis is given on the discussion of the theoretical and practical limits of ionophore-based ion-selective electrodes, with a special focus on electrode sensitivities, characterization of selectivities and dramatic improvements in detection limits. Advances in ionophore design and in the underlying model assumptions are also discussed. It is shown that a multitude of exciting new research possibilities have recently emerged in this well±established ®eld.

A fast and convenient method is reported for preparing ion-selective electrode membranes based on bisphenol A epoxyacrylate, 1,6-hexanedioldiacrylate and benzophenone photoinitiator. A calcium-selective electrode is used as example; responses are Nemstian in the range 1O-'-lO-5 M with the calcium sa

We have developed a new method for the integration of ion-sensitive membranes and silicon sensor chips. The ion-sensitive membrane is deposited in pyramidal containments produced on silicon by an anisotropic etching technique. Here we demonstrate the application of this method to the development of

A photocured sodium ion-selective electrode, based on the ionophore N,N-dibenzyl-N,N'-diphenyl-1,2-phenylenedioxydiacetamide (ETH 157), was developed and evaluated. The robust nature of the photocured membrane made it ideally suited for measurements in flow injection potentiometry. The detection lim
