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

Magnetically Powered Biodegradable Microswimmers [PDF]
Micromachines, 2020 The propulsive efficiency and biodegradability of wireless microrobots play a significant role in facilitating promising biomedical applications. Mimicking biological matters is a promising way to improve the performance of microrobots. Among diverse locomotion strategies, undulatory propulsion shows remarkable efficiency and agility.

Generalized Taylor dispersion of chiral microswimmers. [PDF]
Philos Trans A Math Phys Eng SciTransport phenomena of microswimmers in fluid flows play a crucial role in various biological processes, including bioconvection and cell sorting. In this article, we investigate the dispersion behaviour of chiral microswimmers in a simple shear flow using the generalized Taylor dispersion theory, inspired by biased locomotion of bacterial rheotaxis ...

Coarse Graining Nonisothermal Microswimmer Suspensions
Frontiers in Physics, 2021 We investigate coarse-grained models of suspended self-thermophoretic microswimmers. Upon heating, the Janus spheres, with hemispheres made of different materials, induce a heterogeneous local solvent temperature that causes the self-phoretic particle ...

Theoretical framework for two-microswimmer hydrodynamic interactions
New Journal of Physics, 2021 Hydrodynamic interactions are crucial for determining the cooperative behavior of microswimmers at low Reynolds numbers. Here we provide a comprehensive analysis of the scaling laws and the strength of the interactions in the case of a pair of three ...

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 backward surface motion, i.e. it moves throughout an almost quiescent fluid.
