This book highlights the potential of e-device technology to serve as a successful platform for multiplexed sensing, along with the methods for device fabrication, calibration, and assays in multiple applications. The subsequent sections describe e-device sensing platforms, explore their use, and outline existing limitations and future directions in device development. This work mainly focuses on optical and electrochemical methods of sensing, as these are at the forefront of e-device technology, while also addressing cutting-edge mechanochemical sensing and methods to optimize e-device data and technology via drift correction and calibration and computer modelling. Written for the highly successful series, chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible laboratory prools, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, is an ideal guide for researchers working in a wide variety of fields with a desire to utilize this inexpensive and less specialized technology in their studies.
