Our work on bringing efficient DNP (Ramped NOVEL protocol) to nanoMRI using our force detection based platform has been published in the Science Advances journal. We demonstrated nanoscale pulsed DNP at 6 K and 0.32 T using electrons from the trityl-OX063 radicals, thereby enhancing the average proton polarization by two orders of magnitude. We also showed that the enhanced polarization corresponds to a factor of 200 reduction in the averaging times compared to measurements that rely on statistical fluctuations.
