Molecular Sensors and Nanodevices: Principles, Designs and Applications in Biomedical Engineering, Second Edition is designed to be used as a foundational text, aimed at graduates, advanced undergraduates, early-career engineers and clinicians. The book presents the essential principles of molecular sensors, including theories, fabrication techniques and reviews. In addition, important devices and recently, highly-cited research outcomes are also cited. This differentiates the book from other titles on the market whose primary focus is more research-oriented and aimed at more of a niche market.
