Sentences with phrase «laser tweezers»

Using laser tweezers, a team of Harvard University scientist nudges one sodium and one cesium together to form a molecule.

The scientists then captured the atoms by using the laser tweezers and merged them through a process they called «optical dipole trap.»

The meter - long distances that the research team was able to move the particles could open up new avenues for laser tweezers in the transport of dangerous substances and microbes, and for sample taking and biomedical research.

«Using laser tweezers to study red blood cell invasion gives us an unprecedented level of control over the whole process and will help us to understand this critical process at a level of detail that has not been possible before,» says senior study author Julian Rayner of the Wellcome Trust Sanger Institute.

Not exact matches

The researchers moved these tweezers closer together until the laser beams overlapped, allowing the sodium and cesium atoms to collide.

Such manipulations are routinely done with real atoms trapped in spots of laser light and tugged about with «optical tweezers.»

By looking at their images, the researchers were able to discern which laser beams, or tweezers, were holding atoms and which were not.

To manipulate the foreign DNA, the scientists used optical tweezers, which essentially tweaks a laser beam whose electromagnetic field can grab hold of and transport a plasmid - coated particle.

The method combines two high - tech laboratory techniques and allows the researchers to precisely poke holes on the surface of a single cell with a high - powered «femtosecond» laser and then gently tug a piece of DNA through it using «optical tweezers,» which draw on the electromagnetic field of another laser.

While another laser beam detected the exact location of the cell membrane, they pushed the particle through the pore with the tweezers.

They then dragged each bead across a cell using optical tweezers, a technique that employs a highly focused laser beam to physically move microscopic objects.

Also vital to the work is optical (laser) tweezers, which manipulate objects at the molecular level.

The ability to trap live organisms without harm is surprising, considering that the typical laser intensity at the focal point of the optical tweezers is about 10 million watts per square centimeter.
