The word Nano means one-billionth, and nanoengineers try to improve materials, systems, and devices that are tiny in size. The idea began in 1959, and the term nanotechnology was introduced in 1974. Nanoengineering can be used in various industries, as the materials tend to behave differently at the nanoscale. Nanoengineering is mostly used in nanomedicine, nanotoxicology, and green nanotechnology. Nanoengineering is also used in electronics, energy, and textiles. Students who pursue a career in nanoengineering can work as a materials scientist, research associate, or biomedical device developer. Students who want to get admission to this course need to complete Class 12th with Physics, Chemistry, and Mathematics and have completed their B.Tech degree. Admission to M.Tech in nanoengineering can be through valid scores of the VITMEE or GATE entrance examination.
