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

Microswimmers in vortices: dynamics and trapping
Soft Matter, 2022 We theoretically investigate the dynamics of model microswimmers in singular vortices, discover the existence of bounded orbits and use the model to successfully explain the previously observed depletion zone in bacterial suspensions.

Journal of the Physical Society of Japan, 2021 We propose a model for a thermally driven microswimmer in which three spheres are connected by two springs with odd elasticity. We demonstrate that the presence of odd elasticity leads to the directional locomotion of the stochastic microswimmer.

Effective Viscosity of Microswimmer Suspensions [PDF]
Physical Review Letters, 2010 The measurement of a quantitative and macroscopic parameter to estimate the global motility of a large population of swimming biological cells is a challenge Experiments on the rheology of active suspensions have been performed. Effective viscosity of sheared suspensions of live unicellular motile micro-algae (\textit{Chlamydomonas Reinhardtii}) is far

Nanoerythrosome-functionalized biohybrid microswimmers [PDF]
APL Bioengineering, 2020 Biohybrid microswimmers, which are realized through the integration of motile microscopic organisms with artificial cargo carriers, have a significant potential to revolutionize autonomous targeted cargo delivery applications in medicine. Nonetheless, there are many open challenges, such as motility performance and immunogenicity of the biological ...

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.

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
