Ask a Scientist: What Is the Difference Between Nanoscale and Atomic Scale?

2 minutes

My name is Oliver Brand. I'm a professor in electrical and computer engineering at Georgia Tech in Atlanta.

The question that I'm answering today is about what's the difference between the nanoscale and the atomic scale? Actually, the atomic scale is smaller than the nanoscale. So, when we talk about nanotechnology, typically we look at dimensions between one and one hundred nanometers. So somewhere between atomic spacings and then cell sizes. If we're talking about atomic scale, we really look at the size of atoms, which is below one nanometer. So, nanoscale--between one and one hundred nanometers, atomic scale-- below one nanometer.
