"Sensing and Biosensing with Optically Active Nanomaterials summarizes the potential sensing applications of optically (chromogenic and fluorogenic) active, nano-sized, organic, and inorganic materials for the selective detection of ionic analytes (such as metal ions and anions) in various environmental and biological samples. Sections cover design, synthesis, sensing mechanisms and applications for detecting ionic analytes. Each chapter deals with the sensing applications of one kind of nanomaterial."--
