Micromachines steered by microorganisms

Scanning electron microscope images of the two micromachines. These photos show the “scooter” (on the left) and “rotator” (on the right). Each micromachine was observed in detail and using motion tracking for 70 seconds at a time over several hours. The scale bar length is 10 microns (0.01 millimeter).
