A sharper look at the interior of semiconductors

A research team is developing a high-resolution imaging technique that can be used to determine internal structures in materials and their chemical composition in a non-destructive manner and with nanometre precision

19-Feb-2021

Images provide information – what we can observe with our own eyes enables us to understand. Constantly expanding the field of perception into dimensions that are initially hidden from the naked eye, drives science forward. Today, increasingly powerful microscopes let us see into the cells and ...

How smart, ultrathin nanosheets go fishing for proteins

Faster and simpler production of high-resolution, three-dimensional electron microscopy images of biomolecules

21-Jul-2020

An interdisciplinary team from Frankfurt and Jena has developed a kind of bait with which to fish protein complexes out of mixtures. Thanks to this “bait”, the desired protein is available much faster for further examination in the electron microscope. The research team has christened this ...

Controlling cells with light

Research team develops an active substance that controls an important component of the cytoskeleton with the help of light

19-May-2020

Photopharmacology investigates the use of light to switch the effect of drugs on and off. Now, for the first time, scientific teams from Jena, Munich, and New York have succeeded in using this method to control a component of cells that was previously considered inaccessible. Present everywhere ...

Unraveling the optical parameters: New method to optimize plasmon enhanced spectroscopy

23-Mar-2020

For exploring the nanoscale far beyond the optical resolution limit, tip-enhanced Raman spectroscopy (TERS) is widely recognized as an essential yet still emergent technique. Using this marker-free spectroscopic method scientists gain insights into the structural and chemical composition of ...

Synapses in 3D

Scientists develop new method to map brain structures

12-Nov-2019

Our brain consists of countless nerve cells that transmit signals from one cell to the next. The connections between these cells, the synapses, provide a key to understanding how our memory works. An American research team in collaboration with Rainer Heintzmann from the Leibniz Institute of ...

Tracking the HI virus

Researchers makes visible, how AIDS pathogens multiply in the body

07-Oct-2019

An international team of researchers led by Dr Cyril Favard and Dr Delphine Muriaux from the Montpellier Infectious Disease Research Institute in collaboration with Prof. Dr Christian Eggeling from the Friedrich Schiller University Jena, the Leibniz Institute of Photonic Technology (Leibniz ...

Motion pictures from living cells

Research team improves superresolution microscopy

24-Sep-2019

In order to observe cells at work, researchers have to bypass a physical law. One of the fastest techniques to overcome the resolution limit of classical light microscopy is high-resolution structured illumination microscopy. It makes visible details that are about a hundred nanometres in size. ...

Simulating nature’s cosmic laboratory, one helium droplet at a time

27-Mar-2019

Two astronomers from the Max Planck Institute for Astronomy and from the University of Jena have found an elegant new method to measure the energy of simple chemical reactions, under similar conditions as those encountered by atoms and molecules in the early solar system. Their method promises ...

A quadrillionth of a second in slow motion

Observing and controlling ultrafast processes with attosecond resolution

22-Feb-2018

Many chemical processes run so fast that they are only roughly understood. To clarify these processes, a team from the Technical University of Munich (TUM) has now developed a methodology with a resolution of quintillionths of a second. The new technology stands to help better understand ...

High resolution without particle accelerator

Physicists are first to achieve optical coherence tomography with XUV radiation at laboratory scale

10-Aug-2017

A visit to the optometrist often involves optical coherence tomography. This imaging process uses infrared radiation to penetrate the layers of the retina and examine it more closely in three dimensions, without having to touch the eye at all. This allows eye specialists to diagnose diseases such ...
