The chemical sensor plays an essential role in the fields of environmental conservation and monitoring, disaster and disease prevention, and industrial analysis. A typical chemical sensor is a device that transforms chemical information in a selective and reversible way, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal. Much research work has been performed to achieve a chemical sensor with such excellent qualities as quick response, low cost, small size, superior sensitivity, good reversibility and selectivity, and excellent detection limit. This book introduces the latest advances on chemical sensors. It consists of 15 chapters composed by the researchers active in the field of chemical sensors, and is divided into 5 sections according to the classification following the principles of signal transducer. This collection of up-to-date information and the latest research progress on chemical sensor will provide valuable references and learning materials for all those working in the field of chemical sensors.

This book covers optical chemical sensing by means of optical waveguides, from the fundamentals to the most recent applications. The book includes a historical review of the development of these sensors, from the earliest laboratory prototypes to the first commercial instrumentations. The book reprints a lecture by the Nobel Laureate Charles Townes on the birth of maser and laser, which lucidly illustrates the development of new science and new technology.

Key features include: Self-assessment questions and exercises Chapters start with essential principles, then go on to address more advanced topics More than 1300 references to direct the reader to key literature and further reading Highly illustrated with 450 figures, including chemical structures and reactions, functioning principles, constructive details and response characteristics Chemical sensors are self-contained analytical devices that provide real-time information on chemical composition. A chemical sensor integrates two distinct functions: recognition and transduction. Such devices are widely used for a variety of applications, including clinical analysis, environment monitoring and monitoring of industrial processes. This text provides an up-to-date survey of chemical sensor science and technology, with a good balance between classical aspects and contemporary trends. Topics covered include: Structure and properties of recognition materials and reagents, including synthetic, biological and biomimetic materials, microorganisms and whole-cells Physicochemical basis of various transduction methods (electrical, thermal, electrochemical, optical, mechanical and acoustic wave-based) Auxiliary materials used e.g. synthetic and natural polymers, inorganic materials, semiconductors, carbon and metallic materials properties and applications of advanced materials (particularly nanomaterials) in the production of chemical sensors and biosensors Advanced manufacturing methods Sensors obtained by combining particular transduction and recognition methods Mathematical modeling of chemical sensor processes Suitable as a textbook for graduate and final year undergraduate students, and also for researchers in chemistry, biology, physics, physiology, pharmacology and electronic engineering, this bookis valuable to anyone interested in the field of chemical sensors and biosensors.

This book introduces the principles and concepts of chemical and biochemical sensors for analyzing medical as well as biological samples. For applications like analyzing or monitoring gastric juice or blood plasma, the potential of sensors is exceptionally large. Focussed on these applications, the interpretation of analytical results is explained. Specific advantages are compared to other analytical techniques. Numerous tables with data provide useful information not easily found elsewhere and make a handy source of reference. Ursula E. Spichiger-Keller is head of the Center for Chemical Sensors/Biosensors and Bioanalytical Chemistry at the Swiss Federal Institute of Technology (ETH) in Zurich.

This book is a lucid presentation for chemists, electrical engineers, surface scientists, and solid-state physicists, of the fundamentals underlying the construction of simple and small chemical sensors. The first part of the book is a review of the theoretical background in solid state physics, chemistry and electronics. Semiconductor and solid electrolyte bulk models are reviewed as well as solid/gas and solid/liquid interface models. Membranes and catalysis theory are also covered expansively. The second part is a discussion of more complete sensor devices, their essential components, and of the important developments in this area over the last fifteen to twenty years. The book provides guidance through the multidisciplinary world of chemical sensors. It should be understandable to students with some training in physics and chemistry and a general knowledge of electronics. Finally, comments on economic considerations in the development of new sensor products and suggestionsfor future research and development should be of value to company R&D planners.

Advances in materials science and engineering have paved the way for the development of new and more capable sensors. Drawing upon case studies from manufacturing and structural monitoring and involving chemical and long wave-length infrared sensors, this book suggests an approach that frames the relevant technical issues in such a way as to expedite the consideration of new and novel sensor materials. It enables a multidisciplinary approach for identifying opportunities and making realistic assessments of technical risk and could be used to guide relevant research and development in sensor technologies.

This interesting book covers latest aspects of a highly sophisticated technology; results treated in critical detail; demonstrates applicability of this technology to practical problems in process control, biochip methods, clinical analysis, environmental sciences

Chemical Sensor Technology is a series of annual reviews reporting the latest progress being made in research and technology, both basic and applied, regarding chemical sensors. Chemical sensors continue to grow rapidly in importance encompassing a broad spectrum of technologies covering safety, pollution, fuel economy, medical engineering and industrial processes. Various types of chemical sensors have been devised for detection and monitoring of chemical substances in gases, solutions and organisms, and much work is being done to produce sensitive, selective, reliable and inexpensive sensors. The series aims at contributing to the progress of research and development of chemical sensors. Contributors to the individual volumes are carefully selected by an international editorial board who ensure that as many innovative studies as possible are included. Each article describes a specific topic and is the original work of an expert working in the front lines of chemical sensor research. Contributors are encouraged to describe not only the academic or technological essence of the subject, but also the background and philosophy, evaluation and achievements and future problems. In this way, each topic is described in sufficient depth so as to be useful and stimulating to readers.
