Imaging local diffusion in microstructures using NV-based pulsed field gradient NMR

Robin D. Allert – @robinallert

Understanding diffusion in microstructures is crucial in many scientific fields. Here, we introduce nitrogen-vacancy (NV) center-based nuclear magnetic resonance (NMR) spectroscopy as a powerful tool to probe diffusion. We combined pulsed gradient spin echo (PGSE) with NV-NMR spectroscopy, allowing local quantification of the anisotropic molecular diffusion and flow within microstructures.
