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.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
