Pretty choosy: The selectivity filters of biological ion channels serve as inspiration for the development of ionophore-modified solid-state nanopores exhibiting extraordinary ion selectivity (see picture). Potentiometric transduction is introduced as a simple means to demonstrate the ion-sensing capability of such nanopores.
