Research team decodes symbiotic interactions in marine algae using raman spectroscopy

Implications for biotechnology and environmental protection

02-Oct-2024 - In a recent study, researchers from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Friedrich Schiller University Jena have shown how they can non-invasively and non-destructively investigate the growth and interactions of the green alga Ulva and its bacterial community using ...

Artificial intelligence for better diagnostics

Standardized methods facilitate the evaluation of Raman spectra

15-Dec-2021 - Light-based methods are increasingly used for analytical problems in the fields of health, environment, medicine and safety. Raman spectroscopy is a suitable method in this context. The measurement data collected in this process are complex and extensive molecular fingerprints. Artificial ...

Bacterial toxin blinds algae

Chemical “fingerprints” reveal the “murder weapon”

18-Aug-2021 - University of Jena researchers have discovered a bacterial toxin that destroys the colour pigments in the eyespot of the single-cell green alga Chlamydomonas reinhardtii. Together with another toxic substance, the bacteria of the species Pseudomonas protegens not only disorientate and immobilise ...

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 ...

How the first step affects the (watery) result

German Scientists from Jena and Erlangen-Nürnberg show the way to a more effective creation of hydrogen

28-Jun-2010 - Energy from hydrogen - scientists from all over the world work on this solution to overcome the energy crisis. Amongst other things they try to use the sunlight as driving force for the splitting of water into hydrogen and oxygen. In trying to copy the photosynthesis in the laboratory a team of ...
