Defining key structural and magnetic parameters for standardising magnetic Fe-oxide nanoparticles for biomedical applications
The enormous research in magnetic nanoparticles is due to their appealing size-dependent physical properties. On top of that, promising applications are coming over. One of the more promising and at the same time regulated one, is the utilisation of nanosystems to cure and prevent illnesses. For these biomedic applications, it is mandatory to define the structural and magnetic arrangements of the nanoparticles to then select the key parameters to establish a safe standard. We have carefully selected a group of 4 freeze-dried magnetite/maghemite powders in which we have already performed an exhaustive laboratory characterisation. Our aim is to exploit the unique capabilities of neutron diffraction and define the structural and magnetic structures to compare with previous magnetisation, Mossbauer, TEM and XRD results.
