Biosensors: A Practical Approach (Practical Approach Series)

A biosensor produces a signal proportional in strength or frequency to the concentration of biochemical to which its biological component reacts. This book describes the design, construction, optimization and application of the biological component, its attachment to the transducer and interfacing of the sensing element to appropriate electronic circuitry. In addition, typical applications of the sensor are described along with any pretreatment of the sample that may be necessary to remove interferences or ensure linearity of the sensor's response. A final chapter on the theoretical analysis of biosensor response characteristics is provided to aid in optimizing any device's performance. "Biosensors" provides an up-to-date account of techniques which will find widespread application by life scientists in universities and industry.
