Karlsson, M., J.H. Ardenkjaer-Larsen, and M.H. Lerche, Hyperpolarized 133Cs is a sensitive probe for real-time monitoring of biophysical environments. Chemical Communications, 2017. 53(49): p. 6625-6628.
133Cs NMR is a valuable tool for non-invasive analysis of biological systems, where chemical shift and relaxation properties report on changes in the physical environment. Hyperpolarization can increase the liquid-state 133Cs NMR signal by several orders of magnitude and allow real-time monitoring of physical changes in cell based systems.
