In 1986, American physicist Arthur Ashkin developed a fascinating tool that could gently pick and move microscopic objects like cells and molecules without touching them. This tool, called optical ...

Optical tweezers use laser light to manipulate small particles. A new method has been advanced using Stampede2 supercomputer simulations that makes optical tweezers safer to use for potential ...

Cooling atoms to ultracold temperatures of less than one millikelvin and controlling their internal energy states has led to the development of numerous technologies, including optical atomic clocks 1 ...

(Nanowerk News) Optical tweezers manipulate tiny things like cells and nanoparticles using lasers. While they might sound like tractor beams from science fiction, the fact is their development ...
