Raman Microspectroscopy for Microbiology

Methodology can provide new insights into a variety of key topics in microbiology

17-Jan-2022

Raman microspectroscopy is a fast and non-invasive technology to determine the chemical composition of living microorganisms in near real-time. Jürgen Popp, scientific director of the Leibniz Institute of Photonic Technology, together with an international team of expert scientists, describes the ...

Detect neurodegenerative diseases such as Alzheimer's by a simple eye scan?

Milestone on the way to early diagnostics: Researchers use spectroscopic means to decipher the biochemical composition of the retina

27-Jan-2021

Diagnosing Alzheimer's disease through a non-invasive eye scan long before symptoms appear: a European research team involving Leibniz IPHT has come one step closer to achieving this goal. Using a laser-based method, the researchers have succeeded in discriminating between healthy and Alzheimer’s ...

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 ...

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. ...

Eye scan makes diseases visible at an early stage

10-Sep-2019

More and more people over 50 are suffering from age-related vision disorders. According to the World Health Organization, in four out of five cases they could be avoided if they were diagnosed at an early stage. A European team of scientists, including the Leibniz Institute of Photonic Technology ...
