Nanotechnology, the manipulation of matter at the atomic and molecular scale, is a field brimming with potential. At the heart of this revolutionary domain are nanotechnology engineers, the architects who design and construct the building blocks of tomorrow’s technologies.
What is Nanotechnology Engineering?
Nanotechnology engineering is the application of engineering principles to the design, characterization, production, and application of materials, structures, devices, and systems by controlling shape and size at the nanometer scale. This involves operating at a scale about 100,000 times smaller than the width of a human hair.
A Day in the Life of a Nanotechnology Engineer
