Magnetic Resonance Microscopy and Related Topics

Prof. Dr. Jan Gerrit Korvink [Contact]

The Korvink group focuses a large effort on the development of novel concepts for nuclear magnetic resonance microscopy, i.e., obtaining NMR signals from very small volumes of living or inanimate matter. Our approach is to radically miniaturise various components of the NMR signal chain, from resonator to spectrometer, and to develop bespoke methods for novel applications and experiments. For example, we have developed a variety of NMR micro-resonators, parallel acquisition hardware and signal processing, micro-gradient systems, and novel modular probeheads.

Our NMR research work covers a broad set of topics, from novel manufacturing methods and their associated materials, through design methods for component and system performance prediction, to applications in the life sciences, chemistry, and engineering.

Recent NMR research projects include organ-on-a-chip, NMR metabolomics, CMOS ASIC design, and wafer-scale micromanufacturing. We are also active in the area of hyperpolarisation, expecially with Overhauser DNP in microfluidic systems, and in-situ para Hydrogen based hyperpolarisation. New activities have been initiated in NV centres in diamond.

Further research interests cover nano-optics, simulation tool development, and low cost MEMS and NEMS fabrication.

The Korvink group is funded by the ERC, the EU’s Horizon 2020 programme, the Zeiss foundation, the State of Baden-Württemberg, and the DFG.

The following group leaders’ pages present further information on our specific research topics: Vlad Badilita, Jürgen J. Brandner, Mazin JoudaDanays KunkaArndt Last, Neil MacKinnon, and Dario Mager.
