Chemical sensors and biosensors are among the fastest growing of analytical techniques. This text provides an up-to-the-minute overview of a wide range of sensing systems, discussing the elements of different transducers used in sensors and the selective elements that are employed. The style is relatively non-mathematical and informal in approach. Key features and subjects covered include the following: * Sensors based on both electrochemical and photometric transducers * Mass-sensitive sensors * Thermal-sensitive sensors * Performance factors for sensors * Examples of applications * Detailed case studies of five selected sensors * 30 discussion questions with worked examples and 80 self-assessment questions * 140 explanatory diagrams * An extensive bibliography The book's approach is ideal for students at BTEC (HND and HNC) level, as well as for BSc degree and postgraduate students of analytical and physical chemistry. Chemical Sensors and Biosensors will, in addition, be invaluable to all those concerned with the environmental and biomedical applications of such systemsweiterlesen
