Image of an MTB-microrobot, composed of a PS bead (2 μm in diameter) and an MO-1 cell, within the microfluidic channels executing a turn under the control of the control and tracking system. The dashed circles are used to mark and trace the trajectory of the bead, and the directions of the cut heads are that of the applied magnetic field (enhanced online).
