From: Microfluidic sorting of intrinsically magnetic cells under visual control
Simulations of the magnetic field in the separation channel. Estimates of the magnetic field intensity in the microfluidic channels were performed using finite elements analysis (FEMM). The graph shows the magnetic field across the sorting channel obtained for different concentrations of a ferrofluid, magnetized by a 40 MGOe NdFeB magnet. The magnetic field gradient is indicated by the red lines at three points within the sorting channel. The arrows indicate the range of distances that the bacterial or mammalian cells were covering when initially introduced into the sorting channel.
