Abstract: Systems and methods for generating hyperpolarized target materials are disclosed. The disclosed systems and methods can include hyperpolarizing a compound then transferring polarization to a target material. The compound can be selected to have nuclear spins. The compound can be further selected to have electron spins that, when exposed to certain electromagnetic radiation, exceed a predetermined level of polarization. The compound can be exposed to such electromagnetic radiation, optically hyperpolarizing the electron spins of the compound. Polarization can then be transferred from the electron spins of the compound to nuclear spins of the compound, at least in part by exposing the compound to a magnetic field. The compound can be exposed to the target material before or after pulverizing the compound to increase the surface area of the compound, thereby facilitating transfer of polarization from the compound to the target material.

Abstract: Polarizable diamond materials and methods for obtaining nuclear magnetic resonance spectra of samples external to the diamond materials are described. The diamond materials can include 12C, 13C, substitutional nitrogen, and nitrogen vacancy defects in a crystalline lattice, wherein the substitutional nitrogen concentration is between 10 ppm and 200 ppm, the nitrogen vacancy concentration is between 10 ppb and 10 ppm, and the 13C concentration is greater than 1.1% and not more than 25%. Methods for obtaining nuclear magnetic resonance spectra can include optically pumping a diamond material to generate electron spin hyperpolarization in nitrogen vacancy centers, transferring the electron spin hyperpolarization to nuclei of the sample, and generating a nuclear magnetic resonance spectrum by applying a magnetic field to the sample, exciting the sample with a radio frequency pulse, and detecting a nuclear magnetic resonance response from the sample.

Abstract: Described herein are techniques and methods for measuring the chemical dynamics of a sample by monitoring the longitudinal and/or transverse relaxation rate of hyperpolarized xenon at low magnetic fields using a rubidium magnetometer.

Abstract: Described herein is a technique and method for analyzing the protein binding affinity of a drug. The techniques and methods described herein leverage magnetic resonance techniques such as NMR and MRI to make relaxation measurements of an NMR detectable species. In some embodiments, a rubidium polarizer is used to magnetize 129Xe, which is bubbled into a protein solution. The magnetic decay of the hyperpolarized 129Xe is monitored by measuring the T1 or T2 of 129Xe through NMR spectroscopy.
