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?

You can smell genuine, non-particulate gaseous molecules just fine. The issue is that there’s a large class of compounds that will form actual particles, and this phenomenon can be responsible for a surprisingly large fraction of smog.
