Scientists succeeded in imaging the photocatalytic function of nanoparticles with unprecedently high resolution, which may provide a new tool for nanotechnology and optical manipulation of tiny ...

Optical manipulation of matter by using the mechanical action of light is one of the vibrant subjects of micro and nanoscience. In 2018 the Nobel Prize in physics was awarded to Arthur Ashkin for the ...

A method of optically selecting and sorting nanoparticles according to their quantum mechanical properties has been developed by researchers in Japan. The method could prove a crucial tool for makers ...

Communication between cells in living systems is a complex process, but known to involve small structures termed vesicles that transport material within and outside the cell. Nanoscale extracellular ...

Light does more than illuminate the world—it can also push and twist matter. It was back in the 1870s that James Clerk Maxwell first predicted that light carries momentum and can exert pressure on ...

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 ...
