Experiments with targeted cancer cell treatment using magnetically actuated tri-bead/azo/DOX microrobots. (A) Movement position and swimming posture of a tri-bead microrobot at different times in the chamber with cancer cells. The Red circle indicates microrobot position. The rotation frequency of the actuation field is chosen as 5 Hz in the experiments. (B) Illustration of the magnetic control system and the experimental setup. The tri-bead/azo/DOX microrobots were placed in the right chamber and the H1299 cells were placed in the left chamber. (C) Cellular uptake tested performed using a confocal laser scanning microscope (CLSM), blue: DAPI; red: DOX.
