Comparisons have been made between sodium ion-sensitive field-effect transistors (ISFETs) based on silicone-rubber membranes and plasticized poly(viny1 chloride) (PVC) membranes of highly dispersible calix[4]arene ionophores, regarding their applications to sodium assay in blood sera and urine. The
