For only a few years, it has been possible to resolve biological structures down to the molecular scale with light microscopy, termed super-resolution microscopy. This has led to a number of new insights into biological processes.
The scheme shows a rectangle crafted from DNA with two lines of fluorophores at a distance of 70 nm. With a perfectly aligned super-resolution microscope, these lines can be resolved as is visible in the image on the right. This approach allows the construction of a multitude of structures for various types of super-resolution microscopy.
This research has been funded by the German Research Foundation (DFG) and the Biophotonik IV program of the Federal Ministry of Education and Research (BMBF). The results possess large economic potential as manufacturers of microscopes (e.g. Leica or Zeiss) started to bring „super-resolution microscopes“ to market. In the future, the nanorulers will be distributed by the spin-off company STS Nanotechnology.
Metrology in Braunschweig:
Not only the National Metrology Institute (PTB) is based in the city. A number of institutes bundled in the Metrology Initiative Braunschweig is developing new metrological methods.

Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
