ANALYTICAL ELECTROCHEMISTRY

The goal of this textbook is to cover the full scope of modern electroanalyti-cal techniques and devices. The main emphasis is on electroanalysis, rather than physical electrochemistry. The objective is to provide a sound under-standing of the fundamentals of electrode reactions and the principles of elec-trochemical methods, and to demonstrate their potential for solving real-life analytical problems. The high performance, small size, and low cost of elec-trochemical devices has led to many important detection systems. Given the impressive progress in electroanalytical chemistry and its growing impact on analytical chemistry, this work offers also an up-to-date, easy-to-read presen-tation of more recent advances, including new methodologies, sensors, detec-tors, and microsystems. The book is suitable for a graduate-level course in electroanalytical chemistry or as a supplement to a high-level undergraduate course in instrumental analysis. It should also be very useful to those consid-ering the use of electroanalysis in their laboratories. The material is presented in six roughly equal chapters. The first chapter is devoted to fundamental aspects of electrode reactions and the structure of the interfacial region. Chapter 2 discusses the study of electrode reactions and high-resolution surface characterization. Chapter 3 gives an overview of finite-current-controlled potential techniques. Chapter 4 describes the electro-chemical instrumentation and electrode materials (including new and modified microelectrodes). Chapter 5 deals with the principles of potentiometric meas-urements and various classes of ion-selective electrodes, while Chapter 6 is devoted to the growing field of chemical sensors (including modern biosen-sors, gas sensors, microchip devices, and sensor arrays). Numerous up-to-date references, covering the latest literature, are given at the end of each chapter. By discussing more recent advances, this book attempts to bridge the common gap between research literature and standard textbooks. This third edition of Analytical Electrochemistry is extensively revised and updated, and reflects the rapid growth of electroanalytical chemistry since 1999. It contains a number of new topics, including DNA biosensors, imped-ance spectroscopy, detection for capillary electrophoresis, diamond electrodes, carbon-nanotube- and nanoparticle-based assays and devices, large-amplitude AC voltammetry, microfluidic (“lab on a chip”) devices, or molecularly-imprinted polymeric sensors. Other topics, such as the principles of potentio-metric measurements, spectroelectrochemistry, electrochemiluminescence, modified and microelectrodes, scanning electrochemical and atomic force microscopies, electrical communication between redox enzymes and elec-trodes, explosive detection, or enzyme and immunoelectrodes, have been greatly expanded. The entire text has been updated to cover the very latest (as of August 2005) developments in electroanalytical chemistry. Numerous new illustrations, worked-out examples and end-of-chapter problems have been added to this edition. Existing figures have been redrawn and improved. In the 5 years since the second edition I have received numerous suggestions, many of which have been incorporated in the second edition. Finally, I wish to thank my wife, Ruth, and my daughter, Sharon, for their love and patience; Vairavan Subramanian and Daphne Hui for their technical assistance; the editorial and production staff of John Wiley & Sons, Inc. for their help and support; Professor Erno Pretsch (ETH, Zurich) for extremely useful suggestions; and the numerous electrochemists across the globe who led to the advances reported in this textbook. Thank you all!
