High-resolution magnetic resonance spectroscopy using a solid-state spin sensor
High-resolution magnetic resonance spectroscopy using a solid-state spin sensor, Published online: 14 March 2018; doi:10.1038/nature25781
The spin-hosting nitrogen–vacancy centres in diamond have the spatial sensitivity to detect the nuclear magnetic resonance (NMR) signals of single molecules. However, the spectral resolution of such schemes is not sufficient to unravel details of molecular structure. David Glenn et al. describe a sensitive magnetometer based on an ensemble of nitrogen–vacancy centres that, when combined with a customized pulsed readout protocol, can achieve a spectral resolution sufficient to resolve key chemical signatures at micrometre-scale spatial resolution. Such a scheme could enable NMR spectroscopy at the scale of single cells.
