This book provides a complete overview of a wide range of nanomaterials from their synthesis and characterization to current and potential applications with special focus on the use of such nano—based products as functional agents in biomedical, environmental and industrial applications. It addresses the intrinsic relationship between aspects involving the synthesis of nanocompounds, their bio—physico—chemical properties and their interactions occurring in biomedical, environmental and industrial matrix. This book is of interest to engineers, academics and research scholars working in these fields.
