Dynamics of magnetic particles in microfluidic channels

Abstract

Many microfluidic systems using magnetic particles are established without a detailed knowledge about the inner physics. The current understanding of the controlled manipulation of magnetic beads is mostly based on the motion of particle compounds but not on the individual bead level. We developed a simulation environment that incorporates magnetic particle dynamics and hydrodynamics in laminar or turbulent flow conditions and in the presence of inhomogeneous external magnetic fields. With increased understanding of the control of magnetic particles existing applications can be improved and new applications can be designed.
