At the current time I see this is front page and has reasonable upvotes, but not one comment.

My guess is that this is highly useful for either:

* Building chips (but it's on a silicon surface, not with silicon)

* Carbon nanotubes (looking forward to a space elevator, folks, one day ;))

* It's a more notable movement forward in nano construction in general and I just know too little to understand its impact.

Given the zero comments to date: would someone who knows this area like to accept an invitation to share something really interesting about this paper, please? :)
