DOI: 10.1126/sciadv.abl3708
Abstract: Signal amplification by reversible exchange (SABRE) creates “hyperpolarization” (large spin magnetization) using a transition metal catalyst and parahydrogen, addressing the sensitivity limitations of magnetic resonance. SABRE and its heteronuclear variant X-SABRE are simple, fast, and… read more here.
