Bacteria can swim upstream by reorienting with respect to fluid flows. Here, the authors observe an oscillatory motion and describe the mechanisms behind these reorientation dynamics, which could help designing strategies for bacterial contamination

Microswimmers learning chemotaxis with genetic algorithms

Autor: Gerhard Kahl, Andreas Zöttl, Maximilian Hübl, Benedikt Hartl

Publikováno v: Proc Natl Acad Sci U S A

Various microorganisms and some mammalian cells are able to swim in viscous fluids by performing nonreciprocal body deformations, such as rotating attached flagella or by distorting their entire body. In order to perform chemotaxis, i.e. to move towa

We use mesoscale simulations to gain insight into the digestion of biopolymers by studying the break-up dynamics of polymer aggregates (boluses) bound by physical cross-links. We investigate aggregate evolution, establishing that the linking bead fra

Dynamics of individual Brownian rods in a microchannel flow

Autor: Andreas, Zöttl, Kira E, Klop, Andrew K, Balin, Yongxiang, Gao, Julia M, Yeomans, Dirk G A L, Aarts

Publikováno v: Soft matter. 15(29)

We study the orientational dynamics of heavy silica microrods flowing through a microfluidic channel. Comparing experiments and Brownian dynamics simulations we identify different particle orbits, in particular in-plane tumbling behavior, which canno

Simulation of microswimmer hydrodynamics with multiparticle collision dynamics*

Autor: Andreas Zöttl

Publikováno v: Chinese Physics B. 29:074701

In this review we discuss the recent progress in the simulation of soft active matter systems and in particular the hydrodynamics of microswimmers using the method of multiparticle collision dynamics, which solves the hydrodynamic flows around active
