The Sensor Series includes books on all aspects of the science and technology of sensors, measuring transducers, sensing systems and their applications. Titles in the series are written mainly at the graduate and professional level and are suitable for instrument and measurement scientists, engineers and technologists in both academe and industry. Unlike physical (e.g. pressure) sensors mass-produced using planar electrochemical technology and silicon micromachining, the manufacture of biosensors (i.e. chemical transducers based on a biologically selective and sensitive element) is currently limited to screen-printed glucose sensors. The purpose of Biosensors: Microelectrochemical Devices is therefore to provide electronic engineers, chemists, materials scientists and biotechnology researchers with an interdisciplinary review of electrochemical theory and microelectronic fabrication techniques and their combination to produce cheap (disposable) compact biosensors for on-the-spot (and even in vivo) measurements.

Chapters 1 and 2 introduce microelectrochemical sensor applications and basic electrochemical principles. Chapters 3 and 4 compare potentiometric, voltammetric and conductometric measurement techniques and detail microelectronic fabrication processes for planar silicon-based IC voltammetric sensors and an alternative thick-film process (elaborated in chapter 6). Chapter 5 evaluates the processing and packaging of CMOS-compatible biosensors realized at K U Leuven and elsewhere. This broad theoretical introduction and comprehensive practical review provides the ideal guide to the exciting possibilities for commercial microelectrochemical biosensing. Book jacket.
