The most advanced technology available today, nanotechnology, has enhanced nearly every aspect of our daily lives.We utilize things made using nanotechnology daily without even recognizing it. In nanotechnology, science, engineering, and technology have all been thoroughly examined at the nanoscale. The main objective of this paper is to understand and manage matter at the nanoscale, having dimensions between 1 and 100 nanometers. By using reductive and additive methods, we are quickly increasing our ability to build larger structures with nanometric accuracy. Nevertheless, nature has honed that many biological processes operate at the nanometric level, and structures typically self-assemble based on the molecular chemistry of their component subunits. In this, the Author focuses on Information technology, homeland security, healthcare, transportation, energy, food safety, and environmental research are just a few of the industries and technology sectors where nanotechnology is significantly advancing, if not revolutionizing.
