Nuclear spin contrast is observed at its best with polarized neutrons. In the presence of paramagnetic centers nuclear spins are polarized by the method of dynamic nuclear spin polarization (DNP). Nuclear spin contrast is strongest with polarized protons. Proton spin contrast in some sense extends the range of magnetic neutron scattering to very dilute paramagnets, hence its interest in structural biology
