Optical nano-tweezers control nano-objects: Trap and move individual nano-object in three dimensions using only light

Researchers have invented nano-optical tweezers capable of trapping and moving an individual nano-object in three dimensions using only the force of light. Using this approach, they have demonstrated trapping and 3-D displacement of specimens as small as a few tens of nanometers using an extremely small, non-invasive laser intensity.
