2D motility characterization and external magnetic steering of RBC microswimmers. 2D motility characterization and external magnetic steering of RBC microswimmers. (A to D) Mean speed distribution and 2D swimming trajectories of (A and B) free bacteria and (C and D) bacteria-driven RBC microswimmers, respectively. Free bacteria displayed a mean speed of 19.5 ± 9.2 μm s−1, whereas the mean speed of RBC microswimmers was 10.2 ± 3.5 μm s−1. (E) Magnetic steering of an RBC microswimmer and change in swimming direction upon change in magnetic field direction (i to iii). Red arrows indicate the direction of the magnetic field (B). The inset shows the five-coil setup used for magnetic steering of the RBC microswimmers. Scale bars, 10 μm. Yunus Alapan et al. Sci.
