Nanotechnology is a field of science and technology that focuses on manipulating matter at the nanoscale, that is, at the atomic and molecular level. This discipline involves the design, fabrication, and use of structures and devices with dimensions on the order of a nanometer, which is one billionth of a meter. Nanotechnology has vast applications in many fields, including medicine, electronics, materials science, energy, and the environment. By harnessing the unique properties of materials at the nanoscale, nanotechnology is paving the way for new scientific and technological advances that could revolutionize many aspects of our daily lives.
