That's a hard question to answer. The earliest nanotechnology is ruby-red stained glass windows made with nanoparticles of gold, but the glassmakers didn't know it was nano. Richard Feynman first predicted nanotechnology in 1959. One possible example of the first nanotechnology is the Scanning Tunneling Microscope, invented in 1981. It was one of the first tools that let us see and manipulate individual atoms.
Gas molecules are even smaller than the nanoscale - at the scale of chemical reactions. The weird new properties of nanoscience are at sizes from around 1-100 nanometers long. Hydrogen atoms are about .1 nanometers across.
Great Educational video-- but does nanotech fabrication and research use particular tools? Electron-microscopes? Do different nanotechnologies have anything in common other than working at a small scale?
Electron microscopes and Atomic Force microscopes are important nanotechnologies. Self-assembly, chemical reactions that cause molecules to create specific structures, is also important.
The one constant idea is that tiny particles have surprising new properties.

Can it be done with gas molecules? Im wandering which properties has a nanoparticle of hydrogen for example.
