Nanorobot with Two Arms is Better Than Single-Armed One

Professor Nadrian Seeman at New York University has emerged as one of the key researchers in bringing the hopes for molecular nanotechnology (MNT) closer to reality.

After having completed his work in 2006 of creating a nanorobot with a single arm, Seeman has taken it a step further by developing a two-armed nanorobotic device that can manipulate molecules within a device built from DNA.

If we can loosely define MNT as we humans being able to make macro-scale things atom-by-atom or molecule-by-molecule with the assistance of computers designing and then assembling materials and structures by placing atoms exactly where we want them to go, then Seeman has managed to get largely there. Except for the part about making macroscale objects, of course.
