Strong magnetic field gradient deflects sedimentation trajectories of high spin hemoglobin RBCs.

<p>Examples of the computer screen output of the CTV software showing the trajectories of A) oxygenated RBCs (low spin hemoglobin) and B) methemoglobin-conatining RBCs (high spin hemoglobin). Note the horizontal component of the cell trajectory due to cell magnetophoresis along the horizontal lines of the magnetic force. The cell magnetophoretic mobility, <i>m</i>, was defined as the horizontal distance traveled by the cell divided by the time of the image sequence acquisition and by the local magnetic energy density gradient (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0039491#pone.0039491.e001" target="_blank">Eqn 1</a> in text).
