Figure 2

(a) Bright-field microscopy image of 36 rotating micromotors (Supplementary Movie 3). The scale bar is 20 μm. (b,c) Array of 16 rotors used to characterize the rotational dynamics (Fig. 4). Cell bodies are clearly visible in fluorescence (c) showing the high occupancy fraction of microchambers. The scale bar is 20 μm for both (b,c). (d,e) Zoomed view on one of the rotors in b,c. Cell bodies are fitted with an ellipsoidal shape shown as a dashed line in e. Solid lines illustrate the construction used to measure the lever arm Inline graphic. The scale bar is 5 μm for both d,e.
