Welcome ! |
We perform research in the field of analytical chemistry. Our main topic is the development of electrochemical sensors for heavy metals, nucleic acids, and other organic molecules. In many cases we make use of the several advantages of electrically heated electrodes (Hot-Wire Electrochemistry). Several types of heated electrodes have been developed during the last years including noble metal wires and layers as well as carbon paste and screen-printed gold and carbon electrodes. For our research, we apply various electrochemical techniques and spectrometric methods such as UV/vis, NMR, ToF-SIMS, and RBS. Latest efforts include studies with impedance spectroscopy and quartz crystal microbalance, as well as nanomachinery such as self-propelled nanomotors and micro-rockets. Originally located at Rostock University (Germany) our lab moved in September 2013 to Manchester Metropolitan University (UK), in August 2014 to SUNY Albany (United States), and in February 2019 back to Germany, where the group will now be a part of the Department of Applied Sciences at Coburg University.
