Principles of Nanotechnology

The interdisciplinary field which focuses on the manipulation and manufacturing of materials and devices on atomic, molecular and supramolecular scale, is called nanotechnology. Nanomaterials are the materials which range between 1 to 100 nm. Molecular nanotechnology is the technology that is used for designing complex structures with the help of mechanosynthesis process. Bottom-up and top-down approaches are the two main approaches used in this field. Some top-down approaches include focused ion beams, solid-state techniques, etc. The bottom-up approaches include molecular-beam epitaxy, supramolecular approaches. Some of the theories where nanotechnology is applied are nanoelectronics, nanomedicine, nanopillars, biosensors, nanorods, drug delivery, etc. This book is a compilation of chapters that discuss the most vital concepts in the field of nanotechnology. It elucidates new techniques and their applications in a multidisciplinary approach. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern concepts and applications of the subject.
