NMR relaxation and magnetic properties of superparamagnetic nanowormsYves Gossuin
Biological Physics Department, Universite de Mons, Mons, Belgium
Contrast Media Mol Imaging 5:318-22. 2010..At high field, the longitudinal relaxation of the worms is less pronounced than for the grains, as expected for SPIOs.
