Optical meta‑conveyors enable programmable nanomanipulation along arbitrary open paths

On-chip Integrated Optical Manipulation Nanophotonics Innovation

Researchers have developed a 'meta-conveyor' using a metasurface of amorphous silicon nanorods to transport nanoparticles along arbitrary open paths. The device allows for forward, stop, and backward motion by switching polarization states, demonstrated through a maze-solving experiment.
