Gases are also made of particles. Molecules that you can smell are easily a nanometer across.

Nanoparticle as a term has a specific technical definition that does not include a random gas made of organic small molecules, which include most molecules we perceive by smell.

  Sure, and most small organic molecules are an order of magnitude smaller than that definition.

  What? Not an a whole order of magnitude.
  I thought most orderants were around 0.5 to 1nm in diameter.

The nanoparticles that are the subject of the article are not single molecules.
