Published in 2019 at "Journal of Fluid Mechanics"

DOI: 10.1017/jfm.2019.751

Abstract: There is an overabundance of microswimmers in nature, including bacteria, algae, mammalian cells and so on. They use flagellum, cilia or global shape changes (amoeboid motion) to move forward. In the presence of confining channels,… read more here.
