Chip-Based Optical Tweezers Levitate Nanoparticles in a Vacuum With an Ultrathin Metalens

Metalens-based design shrinks footprint, making optical traps practical for precision sensing and measurements. Researchers have created tiny chip-based optical tweezers that can be used to optically levitate nanoparticles in a vacuum. Optical tweezers — which employ a tightly focused laser beam to hold living cells, nanoparticles, and other objects — can be used for a […]
