Abstract

A method of hyperpolarisation of nuclear spins in one or more particle(s) moving relatively to a polarisation structure, wherein a polarisation of electron spins in the polarisation structure is transferred to the nuclear spins in the particle(s), wherein for one or more of the moving particle(s) within 20 nm from a surface of the polarisation structure, the correlation time of the interaction with the nearest polarisation structure electron spin due to the molecular motion is larger than the inverse of the nuclear Larmor frequency; the electron spins in the polarisation structure are polarised above thermal equilibrium; and the polarisation transfer is performed resonantly.
