Optical tractor beam traps bacteria Date: December 13, 2016 Source: Universitaet Bielefeld Summary: Up to now, if scientists wanted to study blood cells, algae, or bacteria under the microscope ...

The technique uses a basic, conventional optical microscope, a camera or mobile phone, and dedicated software. The joint research project is published in PNAS.

Molecular microscopy: on the left is an artist’s impression of the microscope objective (silver) used in the experiment to view atoms in a 2D optical lattice formed by red laser beams. The image on ...

If the bacteria with which someone is infected are antibiotic-resistant, physicians need to know so as soon as possible. A simple new system could help, by detecting such resistance in just two ...

Image and description: Diekmann, Huser et al, 2016 Diekmann and colleagues' next steps will be to deploy the combination of fluorescence microscopy and optical tweezers to study cells through ...

Although the new device employs the same principle, it makes use of a considerably simplified system based on a traditional optical microscope. In 2020, while studying the nanomotion of yeast cells, ...

At the macroscopic level that’s familiar to us, birds chirp, whales sing and we talk. But at the microscopic level, our cells pulsate, bacteria swim and pressure waves ripple on a scale… ...

But unlike the optical tweezer, where one single laser beam measures the forces exerted by tiny objects, the micro-ear would use a circle of bead-bearing laser beams to listen to the object in ...

Optical microscopy achieves its highest-ever resolutionThe sharpest images ever achieved by optical means have been produced by researchers in Germany. Stefan Hell and Marcus Dyba of the Max Planck ...

Stefan Hell and Marcus Dyba of the Max Planck Institute for Biophysical Chemistry have used conventional optics to image clumps of bacteria just 33 nanometres across - equivalent to 1/23 of the ...
