Measurements of biomechanical properties inside living cells require minimally-invasive methods. Optical tweezers are particularly attractive as a tool. They use the momentum of light to trap and ...

A new method based on optical tweezers can measure viscoelasticity of biological materials in a simpler and more versatile way. In an article published in Nature Nanotechnology, the researchers report ...

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 ...

Newswise — Optical tweezers use focused laser beams to trap and move tiny particles, but they struggle with high-aspect-ratio nanowires. The elongated shape of these structures creates strong ...
