The use of biosensors is accelerating at an enormous rate. Increasingly robust and rapid sensors are being developed for the detection of a wide range of biological molecules and chemicals within the environment. "Biosensors: Methods Express" is a practical guide to all the major classes of electrical and mechanical biosensors in current use. Every chapter discusses the merits and limitations of potential approaches and then provides selected tried-and-tested protocols, with full guidance to ensure success. This book is one which will benefit all researchers who use, or seek to use, biosensors in their research.
