magnetophoresis
Magnetophoresis is the motion of magnetic particles suspended in a fluid under the influence of a spatially varying magnetic field. The force on a particle arises from the contrast between the magnetic susceptibility of the particle and that of its surrounding medium, causing the particle to migrate toward regions of higher or lower magnetic field depending on whether it is more paramagnetic or more diamagnetic than the medium.
In a simple view, the magnetic force scales with the particle volume and the gradient of the
Applications include magnetic separation and purification of cells, proteins, or other labeled species; magnetic bead-based immunomagnetic
Limitations include the need for sufficient magnetic susceptibility contrast, potential aggregation of beads, heating from strong
