There are more issues and complexity to be considered if various micro-electromechanical (MEMS)-type devices are included in the macroelectronics tool kit. As described previously, the materials and devices required for TFTs and circuits can provide adequate electromagnetic (visible and RF) sensitivity for many image-type applications. These materials may also provide satisfactory performance in pressure and strain sensors. Nanotube/nanowire-based devices look promising for various chem-bio sensors.85 However, there is little that is known about the ability to integrate printed microfluidic devices (and other such devices with moving parts) into a roll-to-roll-type process.

Part II (the CD-ROM) contains 53 procedures related to the design and practical applications of the (bio)sensors mentioned in the chapters of Part I. A detailed list of all the materials, reagents, solutions necessary to carry out each of the proposed procedures is given. The necessary steps to prepare the (bio)sensor including its calibration, measurement sequences followed by sample treatment (if applicable) and analysis are described in detail. Each procedure ends with a brief discussion of the typical results expected and selected recommended literature. 

We sincerely hope that this book will be useful not only to researchers working in the field but also to materials scientists, physicists, biologists, physicians, metallurgists, engineers, and all who are actively engaged in solving analytical problems with electrochemical (bio)sensors in real samples. Those researchers in other fields who require novel and easy to apply electrochemical (bio)sensors will also find much of value here. 

Finally we would like to express our gratitude to all the authors for sharing their expertise in the field of electrochemical sensors analysis. The highest quality research presented here will do much to promote real sample analysis with electrochemical (bio)sensors. 

This book on Electrochemical (Bio)Sensor Analysis, edited by S. Alegret and A. Merko< i, is an additional step to advance the field of rapid analysis. It presents advanced sensor developments as well as practical applications of electrochemical (bio)sensors in various fields in a single source. The book contains 38 chapters grouped into seven sections (a) Potentiometric sensors, (b) Yoltammetric (bio)sensors, (c) Gas sensors, (d) Enzyme based sensors, (e) Affinity biosensors, (f) Thick and thin film biosensors, and (g) Novel trends. This interdisciplinary book has contributions from well-known specialists in the field and will be a useful resource for professionals with an interest in the application of electrochemical (bio)sensors. 

The book covers the entire field of electrochemical (bio)sensor design and characterization and at the same time gives a comprehensive picture of (bio)sensor applications in real clinical, environmental, food and industry-related samples as well as for citizens safety/security. In addition to the chapters, this volume offers 53 step-by-step procedures ready to use in the laboratory. This complementary information is offered on a CD-ROM included with the book in order to facilitate hands-on information on the practical use of electrochemical biosensor devices for the interested reader. It is the first time that the Comprehensive Analytical Chemistry series offers such complementary information with detailed practical procedures.

Screen-printed electrochemical (bio)sensors in biomedical, environmental and industrial applications... 

Electrochemical sensors and biosensors offer the achievable opportunity of simplifying the analyses of complex matrices, outside of the laboratory, by suitable modification of appropriate electrode materials [1-5]. One of the most attractive methods for the fabrication of such devices involves the use of screen-printing technology. This allows the (bio)sensors to be manufactured in a wide range of geometries at low cost, particularly when carbon is used therefore, this allows the devices to become disposable [1,2]. A typical screen-printed electrode design commonly used in our laboratories for prototype investigations is shown in Fig. 23.1.
