Department of Radiation research on biological systems
Research in the department of Radiation research on biological systems focuses on understanding the interaction of long-lived radionuclides with biosystems. We are interested in the various levels from biomolecules to individual organisms and complex biocoenoses. On the one hand, the aim is to understand the influence of biological systems on the behavior of radionuclides in the environment (release, mobility and bioavailability). On the other hand, we investigate the effects of radionuclides on the metabolism of cells and the whole organism (uptake, accumulation, chemo- and radiotoxicity) and the resulting dangers for us humans.
Using state-of-the-art molecular biological, spectroscopic and microscopic methods, we work in the fields of repository research to improve the long-term safety of a repository for high-level radioactive waste and radioecology to protect humans and the environment from the dangers of naturally and artificially released radionuclides.
In addition to basic research, our aim is to use the knowledge gained to develop innovative remediation methods and improve models to describe the behavior of radionuclides in the environment.
Interested in working with us?
To support our work, we are always looking for students and interns from the fields of biology, chemistry and environmental sciences who either want to write their thesis with us or simply gain practical experience. Are you interested? Then please get in touch to clarify any questions you may have.
Current research topics
- Determination of the microbial diversity in water and soil environments contaminated with heavy metals and radionuclides as well as in different host rocks for potential radioactive waste disposals
- Microbe-radionuclide-interactions with reference strains and isolates
- Interaction of eukaryotic cells with radionuclides and lanthanides in particular with plants, fungi, sponges and algae
- Investigation of the interaction of selected bioligands and model compounds with f-elements
- Characterization of microbial processes affecting the conditions in deep geological repositories for radioactive waste (e.g. transformation of bentonite as barrier material)
- Calculation and determination of the metal speciation relevant to the environment
- Verification and validation of transport models
- Characterization of particles in the environment relevant to the transport of radionuclides
- Investigation of the transport processes of radionuclides by particles (including microbes) in natural water

Cytotoxicity of Metal-containing Carbon Monoxide-Releasing Molecules: A Current Assessment
Abstract
Carbon monoxide-releasing molecules (CORMs) have drawn attention since the beginning of the century. Since then, many publications have been devoted to optimizing the physicochemical properties of CORMs, with a focus on the release kinetics of CO as a function of external stimuli such as light, enzyme, and redox triggering, as well as ligand exchange and pH changes. This was followed by studies on the use of CORMs and later carbon monoxide-releasing nanomaterials (CORNMs) as pharmaceutical active compounds/materials in biological systems. In this context, there is an ongoing debate as to whether the pharmacological efficacy can be clearly attributed to CO alone or whether CO-free metal fragments or both mechanisms contribute to biological efficacy. This review focuses in particular on CORMs and CORNMs that exhibit cell toxicity and on corresponding characterization methods that allow biological efficacy to be assigned. The methods to be used to obtain reliable information on biodistribution and pharmacokinetic properties, as well as the characterization of the kinetics of controlled CO release in living organisms, are outlined.
