Introduction
Nanotechnology is a term used to define areas of science and engineering in which phenomena occurring at nanoscale dimensions are used in the design, characterisation, manufacture, and applications of materials, structures, devices, and systems. The concept of nanotechnology was first introduced in 1959 when physicist Richard Feynman presented a presentation on making things at the atomic and molecular levels. Nanotechnology is now regarded as the most promising technology of the twenty-first century, and researchers have investigated it as a novel technique in medical research. Nanotechnology will usher in a new era of productivity and prosperity, as seen by increased public funding for nanotechnology research and development over the last decade.1, 2 Nanotechnology can spur economic growth and enhance capacity and quality in industrial sectors. It has substantially contributed to society's welfare and moulded the nature of modern living. It has the potential to significantly alter societal dynamics, economic conditions, and human life.
