In this work the biocompatible molecules - metronidazole and fampridine - were successfully hyperpolarized using parahydrogen via the signal amplification by reversible exchange approach. The nuclear magnetic resonance (NMR) signals from both molecules were detected at zero- to ultralow magnetic field (ZULF) using commercially available rubidium vapor magnetometer from QuSpin.
