Using molecular tweezers to move and image nanoparticles

Haimei Zheng

The ability to manipulate nanoparticles is significant in nanoscale science and technology. As sizes of the objects scale down to sub-10 nm regime, it imposes a great challenge for the conventional optical tweezers. There has been much effort to explore the alternative manipulation methods and the approaches include using plasmonic nanostructures, electron beams, scanning probes, etc. In this paper, an overview of the latest advances in trapping and manipulation of nanoparticles with the focus on the emergent electron tweezers is provided.
