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
Advanced Optical Materials
Abstract: Nitrogen-vacancy (NV) centers in diamond are optically addressable spin defects with great potential for nanoscale quantum sensing. A key application of NV centers is the detection of external spins…
Nature Biotechnology
Abstract: Optically addressable spin systems have been widely studied for quantum-sensing applications. In this work, we demonstrate that photogenerated spin-correlated radical pairs in certain flavoproteins,…
Review of Scientific Instruments
Abstract: We developed an optically detected magnetic resonance setup designed for compatibility with a widely used, commercially available helium bath cryostat equipped with a variable temperature insert. The…
Journal of Magnetic Resonance Open
Abstract: Nitrogen-vacancy (NV) centers in diamond are leading platforms for quantum sensing, yet efficient control of macroscopic ensembles remains challenging. While resonant structures offer high…
Nature Communications
Abstract: Battery development pivots around understanding the complex processes governing battery operation and degradation. Most degradation pathways link structural and chemical inhomogeneities with strongly…
Physical Review Applied
Abstract: Optically active solid-state spin systems have been extensively studied in quantum technologies. We introduce a new readout scheme, termed "time-To-space"(T2S) encoding, which decouples spin…
Nature Communications
Abstract: Microscopy enables detailed visualization and understanding of minute structures or processes. While cameras have significantly advanced optical, infrared, and electron microscopy, imaging nuclear…
ACS Central Science
Abstract: How life developed in its earliest stages is a central but notoriously difficult question in science. The earliest lifeforms likely used a reduced set of codon sequences that were progressively…
Nature Communications
Abstract: Spin defects in semiconductors are widely investigated for various applications in quantum sensing. Conventional host materials such as diamond and hexagonal boron nitride (hBN) provide bulk or…
Applied Physics Express
Abstract: Optimal conditions for creating shallow ensemble nitrogen-vacancy (NV) centers in a 12C-enriched diamond were investigated. NV spin properties, created by implantation of 15N+ ions with 2−5 keV…
