Abstract
Here we report a novel experimental platform in which epi-fluorescent and differential interference contrast (DIC) imaging are used to simultaneously image non-stained bull sperm and measure the flow field around the swimmer using micron-resolution particle image velocimetry (μPIV). The results reveal the existence of four counter-rotating vortices that blink in relation to the roll angle of the swimmer. The development of this technique provide new opportunities for understanding locomotion of microswimmers at small scales.
