A new measurement theory for dual-trap optical tweezers shows researchers for the first time how to easily optimize their experiments to limit noise from Brownian movement.

Optical Tweezers use light to move objects as small as a single atom. Optical tweezer systems use a laser beam focused by a high-quality microscope objective to produce an "optical trap" which is ...

This tool, called optical tweezers, uses a focused laser to hold and manipulate objects. Even after 48 years, optical tweezers are still very relevant, and physicists continue to use this ...

"Unlike optical lattices, tweezers allow greater freedom to arrange atoms in customizable geometries and enable real-time reconfigurations of the particles," explains Grün.
