Abstract
Section titled âAbstractâDynamic nuclear polarization (DNP) of molecules in a solution at room\ntemperature has potential to revolutionize nuclear magnetic resonance\nspectroscopy and imaging. The prevalent methods for achieving DNP in solutions\nare typically most effective in the regime of small interaction correlation\ntimes between the electron and nuclear spins, limiting the size of accessible\nmolecules. To solve this limitation, we design a mechanism for DNP in the\nliquid phase that is applicable for large interaction correlation times.\nImportantly, while this mechanism makes use of a resonance condition similar to\nsolid-state DNP, the polarization transfer is robust to a relatively large\ndetuning from the resonance due to molecular motion. We combine this scheme\nwith optically polarized nitrogen vacancy (NV) center spins in nanodiamonds to\ndesign a setup that employs optical pumping and is therefore not limited by\nroom temperature electron thermal polarisation. We illustrate numerically the\neffectiveness of the model in a flow cell containing nanodiamonds immobilized\nin a hydrogel, polarising flowing water molecules 4700-fold above thermal\npolarisation in a magnetic field of 0.35 T, in volumes detectable by current\nNMR scanners.\n
