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

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' ...

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 ...

If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At least not without a liberal amount of adhesive, water or some other ...

A tiny, first-of-its-kind, nanoscale demonstration shows how we could one day send a spacecraft to another star, within a ...

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 ...

Light near the surface of ultra-thin optical fibers allows sorting of chiral nanoparticles based on their handedness.

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 ...
