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
