Dynamic Characteristics of Superparamagnetic Iron Oxide Nanoparticle in a Viscous Fluid under an External Magnetic Field

摘要

The prediction of the Superparamagnetic iron oxide nanoparticle (SPION) movement in biological systems is one of the most important parameters for the biomedical application of SPION. We proposed a fast solving technique combined with finite element method for analyzing the dynamic characteristics of SPION in a viscous fluid under an external magnetic field. Using this numerical modeling, the effective system dimensions, external magnetic field, particle size, and magnetization can be estimated.
