Covering both theory and applications, New Optical Sensor and Assays for Biophotonic Applications introduces examples of common optical sensors and assays; presents fundamentals such as laser sources, detectors, and fiber optics; and explores various applications. This text demonstrates how assays can be performed at the level of cells, which provides direct correlation with specific biological events in the cell, or at the level of molecules, which is typically conducted in a high-throughput manner. It examines the need to refine existing optical labels for molecular imaging and to develop new ones. This well-illustrated book is part of the new series Biophotonic Science and Engineering.
