I fully support research like this, because it's always good to get proper data about phenomena. However, I can't help feeling that the results are unsurprising: how could you smell the scented candles if they weren't producing nanoparticles? Surely the existence or abundance of these nanoparticles was never in question?

By smelling a gas?

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.
