Latest Optical tweezers Stories
Inexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers.
Researchers from the University of York are pioneering the development of electron microscopes which will allow scientists to examine a greater variety of materials in new revolutionary ways.
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.
Tractor beams -- the ability to trap and move objects using laser light -- are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept.
U.S. Naval Research Laboratory researchers Dr. Sean J. Hart, Dr. Colin G. Hebert and Mr. Alex Terray have developed a laser-based analysis method that can detect optical pressure differences between populations or classes of blood cells that does not rely on prior knowledge, antibodies, or fluorescent labels for discrimination.
Improved device eliminates a barrier to handling nanoscale particles.
Sequencing DNA base pairs â€“ the individual molecules that make up DNA â€“ is key for medical researchers working toward personalized medicine.
Illinois researchers have combined two molecular imaging technologies to create an instrument with incredible sensitivity that provides new, detailed insight into dynamic molecular processes.
The tractor beam -- a tool popularized in the realm of science fiction -- has been slowly making its way into the realm of reality, where beams of light are used to pull objects back toward the source of the light.
