Geometry-Controlled Motility of Microswimmers in elementary microfluidic confinements
Marvin Brun-Cosme-Bruny, Philippe Peyla, Salima Rafai
The motility of microswimmers in confined environments is a fundamental problem in active matter physics, with direct implications for microfluidic applications and the understandi…
Universal Trajectories of Motile Particles Driven by Chemical Activity
C. Misbah, M. S. Rizvi, W. F. Hu +3
Locomotion is essential for living cells. It enables bacteria and algae to explore space for food, cancer to spread, and immune system to fight infections. Motile cells display tra…
Motility and Swimming: Universal Description and Generic Trajectories
A. Farutin, M. S. Rizvi, W. F. Hu +3
Autonomous locomotion is a ubiquitous phenomenon in biology and in physics of active systems at microscopic scale. This includes prokaryotic, eukaryotic cells (crawling and swimmin…
Extreme congestion of microswimmers at a bottleneck constriction
Marvin Brun-Cosme-Bruny, Vincent Borne, Sylvain Faure +3
When attracted by a stimulus (e. g. light), microswimmers can build up very densely at a constriction and thus cause clogging. The micro-alga \textit{Chlamydomonas Reinhardtii} is…
Photofocusing: Light and flow of phototactic microswimmer suspension
Matthieu Martin, Alexandre Barzyk, Eric Bertin +2
We explore in this paper the phenomenon of photofocusing: a coupling between flow vorticity and biased swimming of microalgae toward a light source that produces a focusing of the…
The random walk of a low-Reynolds-number swimmer
Michaël Garcia, Stefano Berti, Philippe Peyla +1
Swimming at a micrometer scale demands particular strategies. Indeed when inertia is negligible as compared to viscous forces (i.e. Reynolds number is lower than unity), hydro…
