Sorting of Chiral Microswimmers [PDF]
Soft Matter, 2013 Microscopic swimmers, e.g., chemotactic bacteria and cells, are capable of directed motion by exerting a force on their environment. For asymmetric microswimmers, e.g., bacteria, spermatozoa and many artificial active colloidal particles, a torque is ...

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.

A frictionless microswimmer [PDF]
New Journal of Physics, 2007 We investigate the self-locomotion of an elongated microswimmer by virtue of the unidirectional tangential surface treadmilling. We show that the propulsion could be almost frictionless, as the microswimmer is propelled forward with the speed of the ...

Hydrodynamics can determine the optimal route for microswimmer navigation [PDF]
Communications Physics, 2021 While control theory for optimal navigation is relevant across scales, from aeronautics to targeted drug delivery, the role of thermal fluctuations and hydrodynamic interactions with interfaces, walls and obstacles at the microscale remains an open ...

Microswimmers in Patterned Environments [PDF]
Soft Matter, 2011 We demonstrate with experiments and simulations how microscopic self-propelled particles navigate through environments presenting complex spatial features, which mimic the conditions inside cells, living organisms and future lab-on-a-chip devices.

Microswimmer trapping in surface waves with shear [PDF]
Proceedings of the Royal Society A, 2023 Many species of phytoplankton migrate vertically near the surface of the ocean, in search of either light or nutrients. These motile organisms are affected by ocean surface waves.
