Researchers have finally found a way to make a real-life levitation ray, but it can only lift microscopic material.

or `laser tweezers,'" an accompanying box lists products with price ranges that may imply that these instruments are currently ready for delivery. These products are not projected to be available for ...

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 ...

I always have a set of tweezers in my makeup bag. I use them to maintain my groomed bushy brows and pluck those errant face hairs that bug me. After years of going through cheap drugstore brands ...

Optical tweezers use a highly focused laser beam to hold and move atoms, nanoparticles or micron-sized particles. As the name itself suggests, they are like tweezers made of light, and they allow ...

Optical tweezers and related techniques provide extraordinary ... However, certain requirements such as high-intensity laser beams, sophisticated electrode designs, additional electric sources ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital ...
