Remote control of self-assembled microswimmers.
Galien Grosjean,Guillaume Lagubeau,Alexis Darras,Maxime Hubert,Geoffroy Lumay,Nicolas Vandewalle +5 more
TL;DR: In this article, a magnetocapillary-driven self-assembly, composed of three soft ferromagnetic beads, is able to swim along a liquid-air interface when powered by an external magnetic field.

Journal ArticleDOI
Ribbons of superparamagnetic colloids in magnetic field.
TL;DR: In this paper, the authors present experimental observations of this equilibrium state with a two-dimensional system and compare their data with the predictions of a pre-existing model, which is explained by the formation of ribbon-shaped aggregates.
Journal ArticleDOI
Superparamagnetic colloids in viscous fluids.
TL;DR: This paper shows how viscosity influences the characteristic time of the aggregation process, with experimental measurements in agreement with previous theories on transient behaviour, and performs numerical simulations on equivalent systems with lower viscosities to reduce the numerical simulation time.
Journal ArticleDOI
Statics and dynamics of magnetocapillary bonds.
Guillaume Lagubeau,Galien Grosjean,Alexis Darras,Geoffroy Lumay,Maxime Hubert,Nicolas Vandewalle +5 more
TL;DR: The properties of magnetocapillary bonds are determined by probing them with magnetic perturbations and a model is proposed that can become the basis for elaborate collective behaviors.
