FET Ion-Sensitive Sensors.
FET based ion sensors appear promising as monitoring and diagnostic aids in clinical medicine. The principles underlying these miniaturized probes are outlined. The fifteen year development period, since their original description, is related to problems with reliability, biological compatibility, and incorporation of reference electrodes. Possible solutions to these problems are outlined. Some results of in vivo experimental and clinical measurements are reviewed which demonstrate their promise.
