Programmable artificial phototactic microswimmer
Nature Nanotechnology, 2016Phototaxis 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.

Three-bead steering microswimmers
Physical Review E, 2018The 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 ...

Biohybrid and Bioinspired Magnetic Microswimmers
Small, 2018AbstractMany 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.

Trypanosomes – versatile microswimmers
The European Physical Journal Special Topics, 2016Evolution has generated a plethora of flagellate microswimmers. They populate all natural waters, from the deep sea to the ponds in our neighbourhood. But flagellates also thrive in the bodies of higher organisms, where they mostly remain undetected, but can also become pathogenic.

Optimal strokes for axisymmetric microswimmers
The European Physical Journal E, 2009We present a theory for low-Reynolds-number axisymmetric swimmers and a general strategy for the computation of strokes of maximal efficiency. An explicit equation characterizing optimal strokes is derived, and numerical strategies to obtain solutions are discussed.

Interactions between comoving magnetic microswimmers
Physical Review E, 2008The artificial microswimmer [R. Dreyfus, Nature (London) 437, 862 (2005)] whose mechanism of propulsion is the magnetically driven undulation of a flagellum-like tail composed of chemically linked paramagnetic beads can be used as a physical model with which to study low-Reynolds-number swimming.
