Nanotechnology Engineering is the manipulation of nanomaterials to convert them into useful and effective materials, structures, and devices. The branch of engineering that deals with the study of nanotechnology are known as Nanotechnology Engineering or Nano engineering. Nano engineering is the engineering field focused on the study, development, and refinement of materials at a very small scale. It can be thought of as the practical application of nanoscience, similar to how mechanical engineering applies the principles of physics.
A nanotechnology engineer seeks to learn new things that can change the face of health, science, technology, and the environment on a molecular level. They test for pollutants, create powders to enrich our foods and medicines, and study the smallest fragments of DNA.
