Yes. It illustrates a tool for a specific deposition cycle.

Use the above to build a pipeline of artificial catalytic sites
and active transport to synthesize the basic building blocks
of a primate. Transport molecules or precursors to deposition
site at cryogenic conditions, modifying them in situ if necessary.
Assemble bulk from legos via convergent assembly.

It doesn't matter, because they operate upon a flat surface, and
can be tilted.

The dimer to be deposited is facing you. C-C is 154 pm, C=C is
134 pm. The tool is roughly oval in shape, and has a tip of
just two carbon atoms across. The volume excluded by the tip
is in Fig. 2.

The tool contains carbons and hydrogens (turquoise and white).

That we can create and dissociate individual bonds under
numerical and monkey-driven (grad student) control is hardly
news. The question is how to deposit at a sufficient rate
to be able to build interesting structures, including some
or parts of the deposition system itself.
It is really my view that such systems can be built, and
we should be working on that.

I suggest you read it. It is really quite good.
