Propulsion of magnetically actuated achiral planar microswimmers in Newtonian and non-Newtonian fluids

open access: yesScientific Reports, 2021
Magnetic achiral planar microswimmers can be massively fabricated at low cost and are envisioned to be useful for in vivo biomedical applications. To understand locomotion in representative in vivo environments, we investigated the swimming performance ...

Microswimmers That Flex: Advancing Microswimmers with Templated Assembly and Responsive DNA Nanostructures. [PDF]

open access: yesAcc Mater Res
The concept of micrometer-scale swimming robots, also known as microswimmers, navigating the human body to perform robotic tasks has captured the public imagination and inspired researchers through its numerous representations in popular media.

Inherently Asymmetric Photocatalytic Microswimmers [PDF]

open access: yes, 2021
In this work, photocatalytic bismuth vanadate microparticles of different morphologies were investigated as artificial single.component microswimmers. In the first chapter, the motion mechanism as well as influence factors on the motion behavior such as ...

Simulations of Odd Microswimmers [PDF]

open access: yes, 2023
We perform numerical simulations of odd microswimmers consisting of three spheres and two odd springs. To describe the hydrodynamic interaction, both the Oseen-type and the Rotne-Prager-Yamakawa (RPY)-type mobilities are used. For the Oseen-type mobility,

Learning to cooperate for low-Reynolds-number swimming: a model problem for gait coordination

open access: yesScientific Reports, 2023
Biological microswimmers can coordinate their motions to exploit their fluid environment—and each other—to achieve global advantages in their locomotory performance.

Microswimmers in vortices: dynamics and trapping

open access: yesSoft 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.

Effective Viscosity of Microswimmer Suspensions [PDF]

open access: yesPhysical 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

Confinement induced three-dimensional trajectories of microswimmers in rectangular channels [PDF]

open access: yes, 2023
We study the trajectories of a model microorganism inside three-dimensional channels with square and rectangular cross-sections. Using (i) numerical simulations based on lattice-Boltzmann method, and (ii) analytical expressions using far-field ...

Odd Microswimmer

open access: yesJournal 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.

Gait switching and targeted navigation of microswimmers via deep reinforcement learning

open access: yesCommunications Physics, 2022
Biomedical applications of artificial microswimmers rely on efficient navigation strategies within complex and unpredictable fluid environments. Here, the authors use artificial intelligence to model and design microswimmers that are capable of self ...
