TL;DR: High field NMR studies of metal nuclei provide insight into the uptake and release of metallopharmaceuticals from the blood plasma proteins albumin and transferrin and the use of 31 P cross-polarization magic angle spinning NMR spectroscopy to investigate the structures of bioactive metal phosphine complexes in the solid state is described.
