Optical tweezers are a non-contact tool that uses laser beams to trap and manipulate tiny objects.

MIT researchers developed a silicon-photonics-based optical phased array (OPA) which could open the door to significant progress in medical diagnostics, biological research, and even in-vivo (in the body) applications.

The new type of optical tweezing system was developed using an approach called optical phased arrays.
