Stirring by periodic arrays of microswimmers [PDF]
Journal of Fluid Mechanics, 2016 The interaction between swimming micro-organisms or artificial self-propelled colloids and passive (tracer) particles in a fluid leads to enhanced diffusion of the tracers. This enhancement has attracted strong interest, as it could lead to new strategies to tackle the difficult problem of mixing on a microfluidic scale. Most of the theoretical work on

Dynamics of microswimmers near a soft penetrable interface
Physical Review Research, 2022 Few simulations exist for microswimmers near deformable interfaces. Here, we present numerical simulations of the hydrodynamic flows associated with a single microswimmer embedded in a binary fluid mixture. The two fluids demix, separated by a penetrable

Anomalous rheology of puller-type microswimmer suspensions
Physical Review ResearchWe explore the mechanism underlying the anomalous rheology of puller-type microswimmer suspensions through direct hydrodynamic simulations. Puller-type swimmers generate contractile flow fields along their swimming direction, leading to hydrodynamic ...

Small Methods, EarlyView.Structured illumination provides both propulsion and guidance for faceted BiVO4 microswimmers. Non‐uniform photoactivation and facet‐dependent reactivity steer the particles along light–dark boundaries, where they autonomously follow curves and corners and adapt to changes in the pattern.

Brownian dynamics of a microswimmer [PDF]
The European Physical Journal Special Topics, 2008 We report on dynamic properties of a simple model microswimmer composed of three spheres and propelling itself in a viscous fluid by spinning motion of the spheres under zero net torque constraint. At a fixed temperature and increasing the spinning frequency, the swimmer demonstrates a transition from dissipation-dominated to a pumping-dominated motion

Optimal Control of Slender Microswimmers [PDF]
, 2017 We discuss a reduced model to compute the motion of slender swimmerswhich propel themselves by changing the curvature of their body. Our approach isbased on the use of Resistive Force Theory for the evaluation of the viscous forcesand torques exerted by the surrounding fluid, and on discretizing the kinematicsof the swimmer by representing its body ...

Dynamic Obstacle Avoidance of Metamorphic Microrobots Using Concentric Sector Navigator
Advanced Intelligent Systems, Volume 8, Issue 10, October 2026.Metamorphic magnetic microrobots are navigated using a concentric sector navigator for dynamic obstacle avoidance in both microroller and swarm states. After microroller transport, citrate‐triggered dissolution releases nanoparticles that reassemble into a controllable swarm.
