Ferromagnetic Microswimmers [PDF]
Physical Review Letters, 2008 We propose a model for a novel artificial low Reynolds number swimmer, based on the magnetic interactions of a pair of ferromagnetic particles: one with hard and the other with soft magnetic properties, connected by a linear spring. Using a computational model, we analyze the behavior of the system and demonstrate that for realistic values of the ...

Hydrodynamic Choreographies of Microswimmers [PDF]
Scientific Reports, 2018 AbstractWe unveil orbital topologies of two nearby swimming microorganisms using an artificial microswimmer, called Quadroar. Depending on the initial conditions of the microswimmers, we find diverse families of attractors including dynamical equilibria, bound orbits, braids, and pursuit–evasion games. We also observe a hydrodynamic slingshot effect: a

Self-Propulsion of Two Contacting Bubbles Due to the Radiation Interaction Force
Micromachines, 2023 In this paper, we consider a new bubble-based microswimmer composed of two contacting bubbles. Under the action of an acoustic field, both bubbles are oscillating, and locomotion of the two-bubble system is observed. A theory is developed that allows one

Microswimmers in vortices: dynamics and trapping
Soft Matter, 2022 We theoretically investigate the dynamics of model microswimmers in singular vortices, discover the existence of bounded orbits and use the model to successfully explain the previously observed depletion zone in bacterial suspensions.

Advanced Intelligent Systems, 2020 In nature, most microorganisms have motility, which is essential for their survival or reproduction. To move, some microorganisms have evolved soft spiral‐shaped flagella, which rotate through specialized motors.

Effective Viscosity of Microswimmer Suspensions [PDF]
Physical Review Letters, 2010 The measurement of a quantitative and macroscopic parameter to estimate the global motility of a large population of swimming biological cells is a challenge Experiments on the rheology of active suspensions have been performed. Effective viscosity of sheared suspensions of live unicellular motile micro-algae (\textit{Chlamydomonas Reinhardtii}) is far
