Nanotechnology is a broad field of science and technology that involves the manipulation and control of matter on a nanometer scale (1-100 nanometers). This field encompasses the design, synthesis, characterization, and application of materials, devices, and systems at the nanoscale, which exhibit unique properties and behavior compared to their macroscopic counterparts. Nanotechnology has applications in various industries, including medicine, electronics, energy, and materials science, with the potential to revolutionize fields such as drug delivery, diagnostics, electronics, and sensors. Some key areas of research in nanotechnology include nanomaterials, nanomedicine, nanoelectronics, and nanomanufacturing.
