Abstract

The development of an ion-sensitive field-effect transistor for sodium ions is described. Cahx[4]arene derivatives incorporated in a poly(vinyl chloride)-based membrane provide the selectivity. A poly(2-hydroxyethyl methacrylate) interlayer between the silicon dioxide gate and the sensing membrane is necessary to obtain a Na+-sensitive ISFET with Nernstian behaviour. The potentiometric selectivity coefficients (log Kij pot) for Na+ over K+ and Li+ are ¿1.9 and ¿2.5,
