Scanning electronic microscopes can see and/or manipulate individual atoms. So, the answer to your question is simple: they took a look from the side and confirmed that it's 1 atom thick.

Small correction: Scanning tunneling microscopes can do that. They are basically a very sharp tip scanned across the surface.

Scanning electron microscopes, where a beam of electrons is rastered across the surface can not (yet?) resolve atoms.

* cannot resolve atoms on a surface, in transmission mode (STEM) and with the right sample, as in the article it's another story.

Thanks! You're correct.
