Phase contrast images of cells movement in magnetic field after EDTA treatment. MNP-containing cells detached and moved to the magnet. Cells without MNP (marked with white arrows) detached but kept their positions. Cells shown in the fig. b (marked with black arrows) were moving to the magnet from left part of the sample. a Cells before EDTA treatment; b 30 min of EDTA treatment; c 100 min of EDTA treatment.
