Microtransformers: controlled microscale navigation with flexible robots [PDF]

open access: yes, 2018
Artificial microswimmers are a new technology with promising microfluidics and biomedical applications, such as directed cargo transport, microscale assembly, and targeted drug delivery. A fundamental barrier to realising this potential is the ability to

Anisotropic mesoscale turbulence and pattern formation in microswimmer suspensions induced by orienting external fields

open access: yesNew Journal of Physics, 2019
This paper studies the influence of orienting external fields on pattern formation, particularly mesoscale turbulence, in microswimmer suspensions. To this end, we apply a hydrodynamic theory that can be derived from a microscopic microswimmer model ...

Interaction of the mechanosensitive microswimmer Paramecium with obstacles

open access: yesbioRxiv, 2022
In this work, we report investigations of the swimming behavior of Paramecium tetraurelia, a unicellular microorganism, in micro-engineered pools that are decorated with thousands of cylindrical pillars.

Miniaturization effect of electroosmotic self-propulsive microswimmer powered by biofuel cell

open access: yesROBOMECH Journal, 2019
For future medical microrobotics, we have proposed the concept of the electroosmotic self-propulsive microswimmer powered by biofuel cell. According to the derived theoretical model, its self-propulsion velocity is inversely proportional to the length of

Propulsion Mechanism of Flexible Microbead Swimmers in the Low Reynolds Number Regime

open access: yesMicromachines, 2020
A propulsion mechanism for a flexible microswimmer constructed from superparamagnetic microbeads with different diameters and subjected to an oscillating field was studied experimentally and theoretically herein. Various types of artificial swimmers with

Galvanotaxis of ciliates: spatiotemporal dynamics of Coleps hirtus under electric fields

open access: yesNew Journal of Physics, 2022
Galvanotaxis describes the functional response of organisms to electric fields. In ciliates, the electric field influences the electrophysiology, and thus, the cilia beat dynamics. This leads to a change of the swimming direction toward the cathode.

Emergent behavior in active colloids [PDF]

open access: yes, 2016
Active colloids are microscopic particles, which self-propel through viscous fluids by converting energy extracted from their environment into directed motion.

Stochastic force dynamics of the model microswimmer Chlamydomonas reinhardtii: Active forces and energetics.

open access: yesPhysical Review E, 2021
We study the stochastic force dynamics of a model microswimmer (Chlamydomonas reinhardtii), using a combined experimental, theoretical, and numerical approach.

Dynamics of a linear magnetic "microswimmer molecule"

open access: yes, 2015
In analogy to nanoscopic molecules that are composed of individual atoms, we consider an active "microswimmer molecule". It is built up from three individual magnetic colloidal microswimmers that are connected by harmonic springs and hydrodynamically ...
