Constructing micromachines out of carbon nanotubes can be a tricky business without grippers small enough to manipulate such small objects. An EU funded consortium has developed two examples of functional tweezers that operate on a scale even smaller than optical microscopes can visualize. The NanoHand project, as the effort is dubbed, has achieved the ability to grasp and move around objects smaller than 100 nanometers in size.
Here’s a video of the grippers and software used to manipulate them:
