Active cargo transport by swimming tori. a A timelapse showing the hydro- and electrodynamic attachment of a swimming bimetallic nanorod to a microtori. The scale bar is 7 μm. b A timelapse showing a 3 μm diameter tori transporting numerous bimetallic nanorods. The scale bar is 2.5 μm. c A cartoon showing the vertical orientation of the micoscopic tori relative to the bimetallic nanorods near the surface. The bimetallic nanorods align along the self-generated fluid streamlines of the microscopic tori when nearby. The scale bar is 2.5 μm
