Supramolecular Assays for Mapping Enzyme Activity by Displacement-Triggered Change in Hyperpolarized (129)Xe Magnetization Transfer NMR Spectroscopy.


Reversibly bound Xe is a sensitive NMR and MRI reporter with its resonance frequency being influenced by the chemical environment of the host. Molecular imaging of enzyme activity presents a promising approach for disease identification, but current Xe biosensing concepts are limited since substrate conversion typically has little impact on the chemical… (More)
