Nanoscience is the study of extremely small matter particularly on molecular, super molecular and atomic scale. These matters are used across different disciplines namely physics, biology, chemistry, engineering and materials science. The current areas of research in nanoscience ranges from carbon nanotubes, nanorods, nanomedicine, nanopillars employed in solar cells, nanoparticles in biological imaging, to nanomaterials used in drug delivery. This book is a complete source of knowledge on the present status of this important field. While understanding the long-term perspectives of the topics the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. The rapid progress happening in this field across the globe has been extensively covered in it. For someone with an interest and eye for detail, this text covers the most significant topics of nanoscience.
