A method of hyperpolarizing diamond particles includes applying a laser to a sample of the diamond particles, irradiating the diamond particles with a sweeping microwave to cause diamond polarization, shuttling the diamond particles through a magnetic field to detectC nuclei in the diamond particles, and relaying the diamond polarization to nuclear spins to one of a surrounding solid or fluid.

Orientation independent, room temperature, hyperpolarization of diamond nano- and micro-particles

A system can include: a superconducting or permanent magnet; a high field portion corresponding to the superconducting or permanent magnet, wherein the high field has a range of 0.1-20 T; a low field portion positioned outside of the superconducting or permanent magnet, wherein the low field has a range of 0.01 nT-100 mT; a shuttling mechanism configured to deliver a sample between the low field portion and the high field portion; and a polarization sub-assembly configured to hyperpolarize the sample while the sample is within the low field portion. A device can be configured to cause nuclear spin hyperpolarization in diamond particles such that the hyperpolarization is transferable to at least one of an external liquid or an external solid. A process of hyperpolarizing substances can include applying optical illumination to the substance, irradiating the substance with a series of microwave signals as one of either a single signal or as a frequency comb to hyperpolarize the nuclei in the substance, and relaying polarization to nuclear spins of one of a surrounding solid or fluid.
