Current Research Actvities
The group is currently synthesizing new magnetic carrier materials and functionalizes them with stabilizing chemicals. In the laboratory, methods for the synthesis of peptides are being developed in order to carry out experiments with a large number of different peptides and under low cost conditions. The interaction of the peptides with target particles should also be optimized and target material be examined in detail for its chemical and physical properties. Current projects can be found under the following link.

‘Bio-fishing’ for rare earths: How protein fragments can be used for the recycling of electronics waste
Without important key elements such as copper or rare earth metals, the electronics industry would grind to a halt and electricity would cease to flow. End-of-life products like discarded energy-saving lamps, mobile phones and computers could provide an important secondary source for these valuable elements; however, they are difficult to recover. Unless, that is, small protein fragments are used to ‘fish’ them out – a technique described by researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Bergakademie Freiberg in an article published in the specialist magazine Research in Microbiology.
