Nanoscale science and technology have occupied centre stage globally in modern scientific research and discourses in early twenty first century. The enabling nature of the technology makes it important in modern electronics, computing, materials, healthcare, energy and the environment. This volume contains some of the papers presented at the ICANN-2009, the first ever international conference on the subject held in the North-eastern part of India, with aims to promote sharing of new knowledge and exchange of the latest ideas in the field, through deliberations in the conference. The papers presented had been designed to represent the length and breadth of the field, with specific emphasis on the multidisciplinary nature of the subject. The peer reviewed articles contained herein are classified into several important subareas, e.g., nanostructured and nanoscale functional materials, nanobiotechnology, nanocomposites, nanoelectronics and nanosensors, nanomagnetism, computational nanotechnology etc. We hope that the readers would find the articles selected for publication scientifically exciting and useful.
