Scientists develop concept for feedback-controlled optical tweezers.These tweezers made of highly focused laser light can grab cell clusters in a controlled manner and rotate them in any direction.

Researchers demonstrated a new type of optical manipulation: using laser light to pull a macroscopic object. The technology has potential for applications in the continued explorations of Mars.

WASHINGTON — Researchers have developed a way to use laser light to pull a macroscopic object. Although microscopic optical tractor beams have been demonstrated before, this is one of the first times ...
