The way you measure nanotechnology is in nanometers, and one nanometer is a billionth of a meter, and to put some scale to that, if you had a nanoparticle that was one nanometer thick, and you put it side by side, and you had 50,000 of them, you'd be the width of a human hair.

And it has billions of interstitial spaces, and those spaces, along with the nanoparticles, reach up and grab the air molecules, and cover the surface with air.
