Functional Nanomaterials is the first and unique compilation of the state-of-the-art review chapters covering all aspects of functional nanomaterials and their applications. Nanotechnology has led to a profound paradigm shift after the developments in recent years and after being classified as one of the most important areas of impending technology by the U.S. government. Novel functional nanomaterials are the basis of newly emerging nanotechnologies for various device applications. This book with 30 chapters reflects the tremendous world-wide interest in functional nanostructured ­materials. The wide variety of topics covered in this book is interesting for professionals working in the fundamental and applied research. The book covers major classes of nanomaterials such as carbon nanotubes, carbon and polymer nano­fibers, nano­particles, nanocomposites, nanosheets, fullerenes, supramolecular and self-assembled nano­structures, and many other types of nanomaterials. In addition, this book highlights various physico-chemical properties of different nanostructures such as catalytic, dielectric, magnetic, fluorescent and luminescent properties as well as applications of nanomaterials in sensors, photonics, drug delivery, proteomics, biomolecular electronics, and Homeland Security.
