Microscopic metavehicles powered and steered by embedded optical metasurfaces

Daniel Andren et al.

Summary: Utilizing optomechanical effects, optical metavehicles can be constructed for microscopic particles to travel long distances under low-intensity plane-wave illumination and be steered by the polarization of the incident light. Demonstrating movement in complex patterns, self-correcting motion, and application as transport vehicles for microscopic cargoes, including unicellular organisms. The abundance of possible optical metasurfaces suggests the potential for developing a wide variety of metavehicles with specialized functional behaviors.
