Oscillatory rheotaxis of artificial swimmers in microchannels
Nature Communications, 2022 Biological and artificial microswimmers often navigate channels under external flow, where in many biomicroswimmers the active upstream motion is oscillatory. Here the authors demonstrate that regular, controllable, and reproducible oscillatory rheotaxis

Photopatterned microswimmers with programmable motion without external stimuli
Nature Communications, 2021 Maragoni microswimmers show the advantage of self-propulsion but their development is limited by fabrication techniques. Here, the authors use a photopatterning method which allows for a high throughput production of maragoni microswimmers with multiple ...

Dynamics of a microswimmer–microplatelet composite [PDF]
Physics of Fluids, 2020 Guiding active microswimmers by external fields to requested target locations is a promising strategy to realize complex transport on the microscale. For this purpose, one possibility consists of attaching the microswimmers to orientable passive components.

Communications Physics, 2022 Microswimmers are ubiquitous in nature and present highly-dynamic collective motion. This study presents computational simulations of spheroidal model-microswimmers confined between two walls, revealing two collective dynamic states, giant motile ...

Advanced Science, 2022 Catalytic microswimmers that move by a phoretic mechanism in response to a self‐induced chemical gradient are often obtained by the design of spherical janus microparticles, which suffer from multi‐step fabrication and low yields.

Royal Society Open Science, 2023 Confinement increases contacts between microswimmers in dilute suspensions and affects their interactions. In particular, boundaries have been shown experimentally to lead to the formation of clusters that would not occur in bulk fluids.

Catalytically propelled 3D printed colloidal microswimmers [PDF]
, 2020 Synthetic microswimmers are widely employed model systems in the studies of out-of-equilibrium phenomena. Unlike biological microswimmers which naturally occur in various shapes and forms, synthetic microswimmers have so far been limited almost ...

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 ...

Suppression of bacterial rheotaxis in wavy channels
Physical Review Research, 2022 Controlling the swimming behavior of bacteria is crucial, for example, to prevent contamination of ducts and catheters. We show that bacteria modeled by deformable microswimmers can accumulate in flows through straight microchannels either in their ...
