Demonstration of flagellar bundling. (a) Diagram of flagellar bundling. (b) Successive fields shown at 24 Hz (deinterlaced; total time span, 2.92 s); numbers refer to fields, i.e., images obtained at 24 Hz. White outline in fields 10 and 80 represents approximate location of magnetic nanoparticle. Scale bar represents 10 µm. (c) Velocities of the flagellar nanoswimmer before and after bundling. Square symbols represent experimental values for averaged swimming speeds. Circles represent values calculated using the method of regularized Stokeslets.
