In this optical tweezer set-up, the packaging complex is tethered between two beads and coupled to a rotor bead via dsDNA. The middle image is a micrograph of the set-up and on the right is an image ...

MIT researchers have harnessed integrated optical phased array (OPA) technology to develop a type of integrated optical tweezers, akin to a miniature, chip-based “tractor beam”—like the one that ...
