Using solid-state spin defects for Nano & Microscale NMR spectroscopy
Our group uses nitrogen-vacancy (NV) centers in diamonds as atomic-scale sensors. With these quantum sensors, nuclear magnetic resonance (NMR) signals from unprecedented lengths scale down to a few cubic nanometer sample volumes or even single molecules can be detected. We aim to establish NV-diamond NMR as a novel tool in chemistry and life sciences by an interdisciplinary approach at the interface of chemistry, physics, and biology with a focus on the following topics:
•Surface NV-NMR spectroscopy with applications in catalysis and material science
•NV-NMR microscopy for probing metabolism on the single-cell level
•NV-NMR on-a-chip for microscale analysis high-throughput screening
•Development of novel quantum materials with spin defects
