Adsorbents based on renewable raw and waste materials, e.g. from the food industry and agroindustry, are produced via a variety of chemical modifications, thermal treatment, and addition of further functional components, such as abundant minerals like clay. The resulting materials act as adsorbents that can be used for the removal of heavy metals, organic pollutants, pharmaceuticals, pesticides, herbicides, and biological contamination.
The research group of Prof. Joachim Koetz is dealing with the synthesis of nanoparticles of different shape and size and their application as sensor materials and for the surface- enhanced Raman spectroscopy for the detection of molecules and reaction mechanisms. The important thing here is the separation and isolation of anisotropic nanoparticles (nanotriangles and nanostars) and their surface modification. In addition to the self- organization of gold and magnetite nanoparticles, the research is focused on the insertion of these particles into Janus emulsions. This makes it possible to adjust the droplet size of stimuli-sensitive Janus emulsions, and respectively the pore sizes of the resulting aerogels. The ultralight magnetic aerogels can be used for purifying liquids (dye and oil layer separation).
Antimicrobial resistance (AMR) is one of the most serious issues of today’s public health. This is where the DFG - Emmy Noether research group Polymere Biomaterialien, led by Dr. Matthias Hartlieb, starts searching for possible solutions. The scientists aim to develop membrane active, antimicrobial polymers, which are so selective towards pathogenic bacteria that they compete with conventional antibiotics. Surface coatings (on medical devices or implants) will also be investigated in the future. The advantage of such materials: the development of resistance is almost impossible.
This bioplastic is the first polymerization of levoglucosenyl methyl ether (LME), derived from sustainable feedstock (cellulose), and developed in the research group of Prof. Helmut Schlaad.
