Electromagnetic momentum and optical forces have emerged as pivotal concepts in modern optical science, bridging fundamental physics and advanced technological applications. At its core, ...

Optical manipulation and photophoretic forces offer transformative tools for the control and analysis of aerosol particles. Optical trapping utilises highly focused light beams to exert radiation ...

Light does more than illuminate the world—it can also push and twist matter. It was back in the 1870s that James Clerk ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...

Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That's ...

Alpha Centauri sits more than four light-years away, close enough to fascinate generations of dreamers and far enough to make ...

Light is not only an important carrier of information but also a carrier of energy. When light interacts with matter, it can induce subtle mechanical effects, known as optical forces. This non-contact ...

A research team led by Professor Cheol Song at the Department of Robotics and Mechatronics Engineering, Daegu Gyeongbuk Institute of Science and Technology (DGIST), has successfully developed an ...

New York, NY—January 1, 2025—Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution ...
