When Art Ashkin, Steve Chu, and their colleagues at Bell Labs in Holmdel, NJ, first invented optical tweezers ... When they looked into the trap with a higher-quality microscope, they confirmed what ...

The concept of optical trapping was first proposed in the 1960s and 1970s by Arthur Ashkin, a scientist at Bell Laboratories. In 1970, Ashkin demonstrated that a focused laser beam could trap and ...

The device takes advantage of the phenomenon of levitating nano-objects within a tightly focused laser ... trap, using beams ...

In other words, the single laser optical trap can be displaced at any position in the field of view, which enhances the spatiotemporal versatility of this method." However, the use of a single ...

This study presents a light-driven microrobot for precise nanoparticle manipulation, utilizing plasmonic nanomotors to ...

This enables simultaneous manipulation of trapped molecules of interest and imaging of the dynamics of individual binding events The optical tweezer element of this setup utilises focused laser light ...

These optical systems are combined ... 3-dimensional magneto-optical trap (3D-MOT). The challenge that researchers face is how to replicate the laser and optics functions onto a small, durable ...
