Latest Optical trapping Stories
Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power “optical nanotweezers” can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples.
A device about the size of a dime can manipulate living materials such as blood cells and entire small organisms, using sound waves, according to a team of bioengineers and biochemists from Penn State.
University of Illinois researchers have shown that by tuning the properties of laser light illuminating arrays of metal nanoantennas, these nano-scale structures allow for dexterous optical tweezing as well as size-sorting of particles.
Not to pick up electrons, but tweezers made of electrons.
Improved device eliminates a barrier to handling nanoscale particles.
There is considerable interest in understanding transport and information pathways in living cells.
Star Trek fans will remember "tractor beams," lasers that allowed the Starship Enterprise to trap and move objects, and now Tel Aviv University is turning this science fiction into science fact â€” on a nano scale.
Professors at the University of Illinois in Champaign say they have discovered a way to better study the bacterial swimming of E.
Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers.
