A Path toward Inherently Asymmetric Micromotors
Advanced Intelligent Systems, 2023 Since the highly cited paper by Purcell postulating the “Scallop theorem” almost 50 years ago, asymmetry is an unavoidable part of micromotors. It is frequently induced by self‐shadowing or self‐masking, resulting in so‐called Janus colloids.

Microbial Adhesion on Circular Obstacles: An Optimization Study
Frontiers in Physics, 2022 Microbial filtration is an important process with applications in environmental, mining, and sanitary engineering. Here, we study the interplay between the motility of microswimmers and the imposed flow to determine the adhesion of bacteria at the ...

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 ...

Photogyrotactic Concentration of a Population of Swimming Microalgae Across a Porous Layer
Frontiers in Physics, 2021 The light environment controls the swimming of microalgae through a light-seeking and avoiding behaviour, which is known as phototaxis. In this work, we exploit phototaxis to control the migration and concentration of populations of the soil microalga ...

Fission and fusion scenarios for magnetic microswimmer clusters
Nature Communications, 2016 The collective motion of microswimmers is determined by not only their direct interaction, but also the hydrodynamics forces mediated by the surrounding flow field.

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots
Advanced Robotics Research, EarlyView.This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.
