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

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
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 ...
