摘要：

The development of an ion-sensitive field-effect transistor for sodium ions is described. Calix[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 K(i,j)pot) for Na+ over K+ and Li+ are -1.9 and -2.5, respectively.
