Electrochemical Sensing: Carcinogens in Beverages (Smart Sensors, Measurement and Instrumentation Book 20)

Annotation This book describes a robust, low-cost electrochemical sensing system that is able to detect hormones and phthalates the most ubiquitous endocrine disruptor compounds in beverages and is sufficiently flexible to be readily coupled with any existing chemical or biochemical sensing system. A novel type of silicon substrate-based smart interdigital transducer, developed using MEMS semiconductor fabrication technology, is employed in conjunction with electrochemical impedance spectroscopy to allow real-time detection and analysis. Furthermore, the presented interdigital capacitive sensor design offers a sufficient penetration depth of the fringing electric field to permit bulk sample testing. The authors address all aspects of the development of the system and fully explain its benefits. The book will be of wide interest to engineers, scientists, and researchers working in the fields of physical electrochemistry and biochemistry at the undergraduate, postgraduate, and research levels. It will also be highly relevant for practitioners and researchers involved in the development of electromagnetic sensors."
