Simulation of a model microswimmer

Journal of Physics Condensed Matter, 2009
We discuss the modelling of a microswimmer that operates in a 'squirmer' mode, by means of stochastic rotation dynamics. The squirmer that we model can easily be tuned between a 'pusher' and a 'puller'. We examine the flows produced by the squirmer and find that there is good agreement between both the predicted and simulated velocities of locomotion ...

Solution‐Synthesized Multifunctional Janus Nanotree Microswimmer

Advanced Functional Materials, 2021
Synthetic active matters are perfect model systems for non-equilibrium thermodynamics and of great potential for novel biomedical and environmental applications. However, most applications are limited by the complicated and low-yield preparation, while a

Ferromagnetic microswimmer

Physical Review E, 2009
The self-propelling motion of the flexible ferromagnetic swimmer is described. Necessary symmetry breaking is achieved by the buckling instability at field inversion. The characteristics of self-propulsion are in good agreement with the numerical calculations of the Floquet multipliers for the ferromagnetic filament under the action of ac magnetic ...

Programmable artificial phototactic microswimmer

Nature Nanotechnology, 2016
Phototaxis is commonly observed in motile photosynthetic microorganisms. For example, green algae are capable of swimming towards a light source (positive phototaxis) to receive more energy for photosynthesis, or away from a light source (negative phototaxis) to avoid radiation damage or to hide from predators.

Biohybrid and Bioinspired Magnetic Microswimmers

Small, 2018
AbstractMany motile microorganisms swim and navigate in chemically and mechanically complex environments. These organisms can be functionalized and directly used for applications (biohybrid approach), but also inspire designs for fully synthetic microbots.

Dance of the microswimmers

Physics Today, 2012
From gut-inhabiting bacteria to sea-dwelling algae, microorganisms display a penchant for coordinated movement. Nonlinear dynamics and fluid mechanics can help explain the curious behavior.

Three-bead steering microswimmers

Physical Review E, 2018
The self-propelled microswimmers have recently attracted considerable attention as model systems for biological cell migration as well as artificial micromachines. A simple and well-studied microswimmer model consists of three identical spherical beads joined by two springs in a linear fashion with active oscillatory forces being applied on the beads ...
