Surface ligand-directed pair-wise hydrogenation for heterogeneous phase hyperpolarization
Published Web Locationhttps://doi.org/10.1039/c5cc08648e
para-Hydrogen induced polarization is a technique of magnetic resonance hyperpolarization utilizing hydrogen's para-spin state for generating signal intensities at magnitudes far greater than state-of-the-art magnets. Platinum nanoparticle-catalysts with cysteine-capping are presented. The measured polarization is the highest reported to date in water, paving pathways for generating medical imaging contrast agents.
