Tunable pheromone interactions among microswimmers
Proceedings of the National Academy of Sciences, 2023 Indirect interactions via shared memory deposited on the field (“field memory”) play an essential role in collective motions. Some motile species, such as ants and bacteria, use attractive pheromones to complete many tasks. Mimicking these kinds of collective behavior at the laboratory scale, we present a pheromone-based autonomous agent ...

Phenotyping single-cell motility in microfluidic confinement
eLife, 2022 The movement trajectories of organisms serve as dynamic read-outs of their behaviour and physiology. For microorganisms this can be difficult to resolve due to their small size and fast movement.

New 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 ...

Miniaturization effect of electroosmotic self-propulsive microswimmer powered by biofuel cell
ROBOMECH 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
Micromachines, 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
New 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.

Droplet microswimmers: chemohydrodynamic and collective effects
, 2023 In this thesis, we investigate the chemohydrodynamics of droplet microswimmers from the individual to the collective scale. A popular experimental realization of a droplet micro-swimmer consists of oil-in-water (alternatively, water-in-oil) emulsions in which the outer phase is a supramicellar surfactant solution that acts as a fuel for droplet ...

Selectively manipulable acoustic-powered microswimmers [PDF]
Scientific Reports, 2015 AbstractSelective actuation of a single microswimmer from within a diverse group would be afirst step toward collaborative guided action by a group of swimmers. Here wedescribe a new class of microswimmer that accomplishes this goal. Our swimmer designovercomes the commonly-held design paradigm that microswimmers must usenon-reciprocal motion to ...
