Opto-thermoelectric microswimmers [PDF]
Light: Science & Applications, 2020 AbstractInspired by the “run-and-tumble” behaviours of Escherichia coli (E. coli) cells, we develop opto-thermoelectric microswimmers. The microswimmers are based on dielectric-Au Janus particles driven by a self-sustained electrical field that arises from the asymmetric optothermal response of the particles. Upon illumination by a defocused laser beam,

Photogravitactic Microswimmers [PDF]
Advanced Functional Materials, 2018 AbstractPhototactic microorganisms are commonly observed to respond to natural sunlight by swimming upward against gravity. This study demonstrates that synthetic photochemically active microswimmers can also swim against gravity. The particles initially sediment and, when illuminated at low light intensities exhibit wall‐bound states of motion near ...

The European Physical Journal Special Topics, 2016 Hot microswimmers are self-propelled Brownian particles that exploit local heating for their directed self-thermophoretic motion. We provide a pedagogical overview of the key physical mechanisms underlying this promising new technology. It covers the hydrodynamics of swimming, thermophoresis and -osmosis, hot Brownian motion, force-free steering, and ...

Ferromagnetic Microswimmers [PDF]
Physical Review Letters, 2008 We propose a model for a novel artificial low Reynolds number swimmer, based on the magnetic interactions of a pair of ferromagnetic particles: one with hard and the other with soft magnetic properties, connected by a linear spring. Using a computational model, we analyze the behavior of the system and demonstrate that for realistic values of the ...

Journal 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.

Biohybrid Microswimmers Against Bacterial Infections [PDF]
Acta Biomaterialia, 2021 AbstractBiohybrid microswimmers exploit the natural abilities of motile microorganisms e.g. in releasing cargo on-demand with high spatial and temporal control. However, using such engineered swarms to deliver antibiotics addressing bacterial infections has not yet been realized.

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.
