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 ...

Emergent behavior in active colloids [PDF]
, 2016 Active colloids are microscopic particles, which self-propel through viscous fluids by converting energy extracted from their environment into directed motion.

Stirring by Periodic Arrays of Microswimmers [PDF]
, 2016 The interaction between swimming microorganisms 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

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.

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 ...

Taxis of Artificial Swimmers in a Spatio-Temporally Modulated Activation Medium [PDF]
, 2017 Contrary to microbial taxis, where a tactic response to external stimuli is controlled by complex chemical pathways acting like sensor-actuator loops, taxis of artificial microswimmers is a purely stochastic effect associated with a non-uniform ...
