Nanotechnology Learn about the very small What is nanotechnology? An exciting area of science and engineering that occurs at the atomic and molecular level — at the 1-100 nanometer range. So small, we can’t see the structures with our eyes. What is nanotechnology all about? The manufacturing and application of materials and systems that have unique properties because of their small size. One nanometer is 10 -9 meters (one billionth) or about 3 atoms long! One of your hairs is about 60 - 80,000 nanometers wide!

What is nanotechnology? An exciting area of science andengineering that occurs at the atomic and molecular level — at the 1-100
nanometer range. So small, we can’t see the structures with our eyes.
What is nanotechnology all about?The manufacturing and application
of materials and systems that have unique properties because
of their small size.
One nanometer is 10-9 meters (one billionth) or about 3 atoms long! One of your hairs is
about 60 - 80,000 nanometers wide!
