Researchers will soon be able to study biological changes at scales and speeds not previously possible to significantly ...

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 ...

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 ...
