Abstract
Comparisons have been made between sodium ion-sensitive field-effect t ransistors (ISFETs) based on silicone-rubber membranes and plasticized poly(vinyl chloride) (PVC) membranes of highly dispersible calix[4]ar ene ionophores, regarding their applications to sodium assay in blood sera and urine. The silicone-rubber membranes are found to possess gre at advantages over the PVC membranes on the application of their ISFET s to serum and urine samples. Hardly any potential deviation is found from sodium-ion calibration plots for the silicone-rubber membrane ISF ETs on the sodium assay even of undiluted samples, whereas the deviati on is serious for the plasticized-PVC membrane ISFETs.
