Clustered core particles for MPI

The potential of clustered core magnetic particles for MPI

We synthesized different iron oxide nanoparticles which show no obvious differences between their structures, yet their MPI efficacy varies significantly. Our results indicate that the structural feature of clustered particle cores and thus, the aqueous synthesis route, indeed holds a currently unknown potential for MPI, which still remains to be explored. Our findings lead us to conclude that the presence of crystallite clusters, their size and the crystallites´ interaction inside the clusters is a determining parameter for a particle´s MPI performance. It will be a matter of further studies to investigate these interactions in more detail in order to allow for an understanding of the structure-efficacy relation and the directed optimisation of iron oxide nanoparticles for MPI applications.
