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 ...

Optothermal nanotweezers, an innovative optical manipulation technique over the past decade, have revolutionized classical optical manipulation by efficiently capturing a broader spectrum of ...

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 ...

MIT researchers have harnessed integrated optical phased array (OPA) technology to develop a type of integrated optical tweezers, akin to a miniature, chip-based “tractor beam”—like the one that ...

The paper is published in the journal Nature. In a world-first, scientists used precisely controlled optical traps, known as "magic-wavelength optical tweezers," to create a highly stable environment ...

A project led by Spain's ICFO research center has developed a novel optical tweezer arrangement able to assess the viscoelastic properties of biological materials. Quantifying the mechanical responses ...

As a precise tool for influencing biofilm growth patterns, laser manipulation could enable biofilms to be used for sensors and more WASHINGTON — Biofilms — slimy layers formed when bacteria stick ...

No matter how small you make a pair of tweezers, there will always be things that tweezers aren’t great at handling. Among those are various fluids, and especially aerosolized droplets, which can’t be ...

(Nanowerk News) Researchers have long sought to develop versatile tools that allow precise manipulation and identification of DNA and other biological nanoparticles. Optical tweezers, which use lasers ...

(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 ...
