摘要
We report synthesis and studies of magnetic suspensions with tunable low-field relaxivities. Using a one-step procedure, we have prepared magnetic fluids composed of polyelectrolyte stabilized magnetite nanoparticles. We have demonstrated the effect of varying the synthetic conditions, in particular, the iron and PSSS polyelectrolyte content for a fixed polymer chain length, on the emergent magnetic resonance properties of the iron oxide nanoparticle suspensions. The new magnetic fluids have a potential for in vivo MRI diagnostics.
