Optimal navigation of microswimmers in complex and noisy environments
New Journal of Physics, 2022 We design new navigation strategies for travel time optimization of microscopic self-propelled particles in complex and noisy environments. In contrast to strategies relying on the results of optimal control theory or machine learning 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 ...

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 ...

Fully Steerable Symmetric Thermoplasmonic Microswimmers
ACS Nano, 2021 A cornerstone of the directed motion of microscopic self-propelling particles is an asymmetric particle structure defining a polarity axis along which these tiny machines move. This structural asymmetry ties the orientational Brownian motion to the microswimmers directional motion, limiting their persistence and making the long time motion effectively ...

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.

Coarse Graining Nonisothermal Microswimmer Suspensions
Frontiers in Physics, 2021 We investigate coarse-grained models of suspended self-thermophoretic microswimmers. Upon heating, the Janus spheres, with hemispheres made of different materials, induce a heterogeneous local solvent temperature that causes the self-phoretic particle ...

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.
