[...] Graphene applications extend to molecular machine systems, too, where graphene can form both strong, stiff structures and excellent bearings to support moving parts. Developments in graphene nanotechnology may be key to the development of nanomechanical systems for atomically precise fabrication. [...]

On the subject of microscopy, coherent x-ray imaging also looks promising. The site says

The full transverse coherence of the LCLS laser will allow single particles to be imaged at high resolution while the short pulse duration will limit radiation damage during the measurement. The instrument will allow imaging of biological samples beyond the damage limit that cannot be overcome with synchrotron sources.

Admittedly, I'm not sure, from the description of the source, whether they can use the transverse coherence of their x-ray source to get a hologram of a single molecule.

Other potentially very use properties of graphene for engineered nano-systems :
- Single sheets of graphene are excellent gas barriers to even hydrogen and helium.

- Excellent 2-Dimensional heat conductor. (think about it for a while )

- By changing the shape and size of the sheet of graphene you change how it interacts with the EM spectrum.

- Conceptually simple way to make a very wide variety of 3 -D shapes : Cut – Stack – (Mechanically) Lock in Place standard sheets of graphene [or Stamp - Stack -(chemically) Stick standard sheets of graphene together.]
