Up to 40 volumes are planned for this concise monograph series, which focuses on the implementation of various engineering principles in the conception, design, development, analysis and operation of biomedical, biotechnological and nanotechnology systems and applications. In this monograph, the authors discuss the current progress in the medical application of impedimetric biosensors, along with the key challenges in the field. First, a general overview of biosensor development, structure and function is presented, followed by a detailed discussion of impedimetric biosensors and the principles of electrochemical impedance spectroscopy. Next, the current state-of-the art in terms of the science and technology underpinning impedance-based biosensors is reviewed in detail. The layer-by-layer construction of impedimetric sensors is described, including the design of electrodes, their nano-modification, transducer surface functionalisation and the attachment of different bioreceptors. The current challenges of translating lab-based biosensor platforms into commercially-available devices that function with real patient samples at the POC are presented; this includes a consideration of systems integration, microfluidics and biosensor regeneration. The final section of this monograph describes case studies of successful impedance-based biosensors for the detection of a range of analytes from small molecules up to whole microorganisms. Finally, the authors put forward future perspectives for the clinical applications of impedimetric biosensors.

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.
