Chapter 27 — Micro-/Nanorobots

Attogram mass delivery from a carbon nanotube

This video shows the mass delivery from a carbon nanotube based on nanorobotic manipulation inside a transmission electron microscope. Copper atoms were driven out from the nanotube due to electromigration. A typical mass flow rate is around 1 atom per microsecond. Applications of this phenomenon in nanorobotic spot welding, bubbling of sphere-on-pillar optical antennas, and direct writing of 3-D metallic nanostructures have been demonstrated.
