The evolution in the nanotechnology world clearly signifies a need for a broader understanding of the subject and this book will contribute to the effort. Nanostructure science and technology is a broad and interdisciplinary area of research and development that has been growing explosively in the past decades. The contents of this book include mainly the fundamentals of nanoparticles, state-of-the-art in synthesis and characterization of nanomaterials, as well the influence of nanomaterials on the analytical systems (macro to micro & lab-on-a-chip) for biomedical, environmental and engineering applications. This book seeks to broaden the understanding of modern developments in nanomaterials and comprises excellent contributions from subject matter experts working on most aspects of nanomaterials and nanotechnology.
