In 1970, Ashkin demonstrated that a focused laser beam could trap and manipulate dielectric particles, laying the groundwork for future optical tweezers (see the original 1970 paper: "Acceleration and ...

Laser ‘tweezers’ help scientists see particles stick in real time At the microscopic level, adsorption is a surface process that occurs when molecules, atoms or ions stick to a surface.

The study is published in the journal Optica. The team's method involved creating "ballistic rotating optical tweezers"—by shining a laser through a microscope and controlling its polarization ...

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 ...
