Abstract:
Development of miniaturized electrochemical sensing systems for in vitro and in vivo biomedical applications is discussed. The systems are based on high sensitivity potentiostatic instrumentation, which is suitable for chemical and biochemical sensors. The in vitro application is an 8 channel hand-held PC-controlled system with user-friendly interface. This is capable of implementing different electrochemical potentiodynamic techniques. The in vivo applications are realized using two approaches: a small sized PCB with commercially available ICs, and a specially developed on-chip system. The performance of the systems is validated through electrochemical characterization of a microarray sensor.
