... to pick up and move individual cells around the surface of a microchip.
Now they have applied the optical tweezers to measuring protein microarchitectures, allowing them to study the forces that give ...
NIST has licensed a patented 'optical tweezers' technique for detecting and measuring very small concentrations of a biological substance, such as a virus on a surface.
Cutting-edge "tweezers" are so sensitive that they can feel the tell-tale tug of tiny concentrations of pathogens in blood samples, yet don't ever need to be sterilized--or even held--as they are ...
... A. R. Hawkins of Brigham Young University, where the optofluidic chips are fabricated.
Optical traps and "optical tweezers" use the momentum carried by the photons in a beam of light to exert forces ...
... State engineers. "Current methods for moving individual cells or tiny beads include such devices as optical tweezers, which require a lot of energy and could damage or even kill live cells," said Tony ...
... the work is focused on very small particles, like atoms, or on larger particles, such as for use as optical tweezers. There is an interim region between atoms and large particles, and that is what we ...
... equivalent of the way static electricity on clothes attracts lint.
This phenomenon is exploited in "optical tweezers" used by physicists to trap tiny objects. The forces tend to pull anything at the ...
... In order to test their hypothesis that heavy handedness can lead to loss of control, the researchers used optical tweezers to grab hold of floating microscopic beads. They then dragged the particles ...
... Professor of Physics at Northeastern University's College of Arts in Sciences, and his research team have developed a method using optical tweezers to better understand how those interactions occur.
... DNA interacts with a potential drug is an important element of DNA therapy research. Scientists have now developed a method using optical tweezers to better understand how those interactions occur.
Researchers have developed a novel technique to measure the strength of the bonds between two protein molecules important in cell machinery: gently tugging them apart with light beams.
... Ostap.
In collaboration with Henry Shuman, PhD, Associate Professor of Physiology, the research team used optical tweezers -- a combination focused laser beam and microscope, of sorts -- to measure ...
... determined easily with high-spatial resolution," says Terao.
The team used optical tweezers – tightly focused laser beams – to control the Z-shaped micro hook and pick up a single ...
... beam.
Nanotubes are known for their strong color-dependant interactions with light. By using an optical tweezer, a device that traps microscopic or nanoscopic objects in laser beams, researchers were ...
