Short summary
The signals that are attainable in conventional NMR are tiny, and consequentially, NMR is often slow and insensitive. The intensity may be increased by hyperpolarization, provided that the spectral quality is essentially preserved. We have recently reported a potentially powerful hyperpolarization scheme, named bullet-DNP (dynamic nuclear polarization). Here, we report a 10-fold improvement in resolution for that method, which may enable new applications in metabolomics and drug discovery.
