Nanostructures are defined as structures that are intermediate between microscopic and molecular structures at nanoscale. These are classified depending on the number of dimensions, into nanostructured surfaces, nanotubes, spherical nanoparticles, etc. These have diverse applications across major domains of medicine, manufacturing, electronics, food science, etc. This book includes some of the vital pieces of studies on the chemistry of nanostructures that are being conducted across the globe. The diverse aspects of nanostructures are also glanced at and their applications as well as ramifications are looked at in detail. It also covers in detail some existent theories and innovative concepts related to the field. This book will prove to be immensely beneficial to students and researchers in the field of nanotechnology.
