Hydrodynamics of an odd active surfer in a chiral fluid
New Journal of Physics, 2023 We theoretically and computationally study the low-Reynolds-number hydrodynamics of a linear active microswimmer surfing on a compressible thin fluid layer characterized by an odd viscosity.

Autonomous elastic microswimmer [PDF]
Europhysics Letters, 2021 Abstract A model of an autonomous three-sphere microswimmer is proposed by implementing a coupling effect between the two natural lengths of an elastic microswimmer. Such a coupling mechanism is motivated by the previous models for synchronization phenomena in coupled oscillator systems.

Geometric Methods for Efficient Planar Swimming of Copepod Nauplii
Micromachines, 2021 Copepod nauplii are larval crustaceans with important ecological functions. Due to their small size, they experience an environment of low Reynolds number within their aquatic habitat.

Periodic and Quasiperiodic Motion of an Elongated Microswimmer in Poiseuille Flow [PDF]
, 2012 We study the dynamics of a prolate spheroidal microswimmer in Poiseuille flow for different flow geometries. When moving between two parallel plates or in a cylindrical microchannel, the swimmer performs either periodic swinging or periodic tumbling ...

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

Magnetically Actuated Colloidal Microswimmers
The Journal of Physical Chemistry B, 2008 To achieve permanent propulsion of micro-objects in confined fluids is an elusive but challenging goal that will foster future development of microfluidics and biotechnology. Recent attempts based on a wide variety of strategies are still far from being able to design simple, versatile, and fully controllable swimming engines on the microscale. Here we

Bacterial Biohybrid Microswimmers
Frontiers in Robotics and AI, 2018 Over millions of years, Nature has optimized the motion of biological systems at the micro and nanoscales. Motor proteins to motile single cells have managed to overcome Brownian motion and solve several challenges that arise at low Reynolds numbers.
