Ask a Scientist: What Is the Nanoscale, and Do Nanomaterials Exist in History?

2 minutes

(Describer) Title: NSF. Ask a Scientist.

Hi, my name is Lisa Friedersdorf, and I'm the director of the National Nanotechnology Coordination Office.

(Describer) Title: Ask a Scientist – Nanotechnology.

Nanotechnology is the control and manipulation of matter at the nanoscale, and this is really tiny. The nanoscale-- a nano is ten to the minus nine meters, or a billionth of a meter. So we're talking about the control and manipulation of matter at the atomic and molecular level. So, while applications in nanotechnology are now in the marketplace, and future applications are on the horizon, there are many examples of nanotechnology in history. Two classic examples are in stained-glass windows, where gold at the nanoscale gave the red pigment. Another classic example is nanoparticles in ancient steels that were used for swords. So while we now have the tools to actually make an image at the nanoscale, there are many examples throughout history that show the application of nanotechnology.
