Working towards the ideal nanoparticle for Magnetic Particle Imaging (MPI)
The performance of magnetic particle imaging (MPI) depends on the properties of magnetic nanoparticles with diameters in the range of 10 to 100 nanometers. The response of the nanoparticles to an externally applied time-varying magnetic field depends on many characteristics of the particles: magnetic properties of the iron core including Neel relaxation and magnetic anisotropy; hydrodynamic and iron core diameters; electrical properties of the non-magnetic coating; and Brownian motion related to the viscosity of the suspension fluid. We will use theoretical models that include these nanoparticle characteristics in order to find the optimal nanoparticle for MPI.
