(Nanowerk News) Researchers have created tiny chip-based optical tweezers that can be used to optically levitate nanoparticles in a vacuum. Optical tweezers — which employ a tightly focused laser beam ...
Given their tiny size, individual atoms are notoriously tricky to see and manipulate, but finding ways to do so would be extremely useful. The invention of the laser in the 1960s eventually led to the ...
Ashkin's discovery has since formed the basis for the development of optical tweezers, a tool frequently used to control the motion of small biological objects and investigate them. Optical tweezers ...
