Nano- and Microscale NMR spectroscopy with spin qubits in diamond — •Nabeel Aslam — Leipzig University

Expanding nuclear magnetic resonance (NMR) spectroscopy to the micro- and nanoscale holds significant potential to advance research across disciplines. Potential applications include the chemical analysis of mass-limited samples, single-cell metabolomics for disease diagnostics, and the detection and characterization of individual proteins, such as functional membrane proteins.

In this talk, I will introduce a novel approach to nano- and microscale NMR using nitrogen-vacancy (NV) centers in diamond. These quantum defects can be optically polarized and read out, enabling highly sensitive detection of nuclear spins with exceptional spatial resolution. This capability is further enhanced through hyperpolarization techniques. I will provide an overview of the state-of-the-art in the field, including advancements in detecting nuclear spins on surfaces, integrating NV-based NMR with microfluidic technologies for high-throughput applications, and employing diffusion NMR to study molecular transport at the nanoscale.

Furthermore, I will discuss how nuclear spins in diamond can serve as quantum memories, enhancing the performance and versatility of NV-based sensing. This highly sensitive and versatile method has the potential to uncover new insights into complex systems in chemistry, biology, and material science.
