Paper Abstract

A brief review of recent advances in biosensor technologies which have contributed to the development of state-of-the-art biomedical microsensors is given. This is followed by a discussion of potential medical applications in the area of diagnosis and monitoring. The combination of IC fabrication technologies with membrane science has led to a new class of chemically sensitive devices. Those show promise of having important advantages over the conventional ion selective electrodes for biomedical applications. They are small, rugged, require only a very small sample of analyte, have a fast response, are inexpensive, and are compatible with microelectronic readouts. In the second part, some specific electrochemical microfabricated sensors will be given. The results of an - integrated multispecies sensor chip for the measurement of pH, Cl , K? and Na+in physiological fluids will be discussed.
