Nanoscience is an interdisciplinary field that have encompassed physics, biology, engineering chemistry and computer science, among others, the prefix nano appears with increasing frequency in scientific journals and the news. Thus, as we increase our ability to fabricate computer chips with smaller features and improve our ability to cure disease at the molecular level, nanotechnology is at the doorstep. Scientists and engineers believe that the fabrication of nanomachines, nanoelectronics and other nanodevices will help to sole numerous problems faced by mankind today related to energy, health and materials development.

The present book is a sincere attempt to make the readers aware of the evolutionary trends underlying modern engineering practice which are grounded not only on the tried and true principles and techniques of the past, but also on more recent and current advances. The book contains polymeric nanofibres, synthesis of nanostructure, analysis of electron currents through nanojunctions, water soluble carbon nanotubes, nanoelectronic switching networks, growth of silica nanorods, magnetic nanostructures, nano machining of microscope tips and carbon nanotubes, nanocrystalline semiconductors and many more. This book will be useful to technocrats, researches new entrepreneurs, technical institutions and introduction to this field.
