Live-cell time-lapse imaging and single-cell tracking of magnetically labeled PC12 cells. A Time-lapse images of a biotinylated cell conjugated to MMP-SA migrating to a permanent magnet. B Phase contrast projection images of PC12 cells in three different time points. C The magnetic field is stimulated by the permanent magnet on the side of the plate, according to measurements. D Linear function representing the distance (μm) over time (ms)
