Steady motions of single spherical microswimmers in non-Newtonian fluids [PDF]
The Physics of FluidsIn biological systems, microswimmers often propel themselves through complex media. However, many aspects of swimming mechanisms in non-Newtonian fluids remain unclear.

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 ...

MRI driven magnetic microswimmers [PDF]
Biomedical Microdevices, 2011 Capsule endoscopy is a promising technique for diagnosing diseases in the digestive system. Here we design and characterize a miniature swimming mechanism that uses the magnetic fields of the MRI for both propulsion and wireless powering of the capsule. Our method uses both the static and the radio frequency (RF) magnetic fields inherently available in

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.

Advanced Robotics Research, EarlyView.Functional surfaces are investigated as a foundation for reconfigurable microscale systems with sensing and actuation capabilities. Advances in additive manufacturing enable our development of planar arrays of hybrid‐material, compliant microdevices that convert environmental stimuli into programmed motion and visual responses.

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.

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 ...
