Microswimmers near surfaces [PDF]
The European Physical Journal Special Topics, 2016 Both, in their natural environment and in a controlled experimental setup, microswimmers regularly interact with surfaces. These surfaces provide a steric boundary, both for the swimming motion and the hydrodynamic flow pattern. These effects typically imply a strong accumulation of microswimmers near surfaces.

Universal entrainment mechanism governs contact times with motile cells [PDF]
, 2017 Contact between particles and motile cells underpins a wide variety of biological processes, from nutrient capture and ligand binding, to grazing, viral infection and cell-cell communication. The window of opportunity for these interactions is ultimately

Surface anchoring controls orientation of a microswimmer in nematic liquid crystal
, 2020 Microscopic swimmers, both living and synthetic, often dwell in anisotropic viscoelastic environments. The most representative realization of such an environment is water-soluble liquid crystals.

From 0D to 3D liquid crystal elastomers architectures: Fabrications and applications
Responsive Materials, EarlyView.This review presents a dimension‐oriented overview of liquid crystal elastomers (LCEs), highlighting their molecular alignment, fabrication strategies, and programmable deformations from 0D particles to 3D architectures. Emphasis is placed on how dimensionality guides design principles, enables diverse actuation modes, and bridges fundamental ...

Reconfigurable artificial microswimmers with internal feedback
Nature Communications, 2021 AbstractSelf-propelling microparticles are often proposed as synthetic models for biological microswimmers, yet they lack the internally regulated adaptation of their biological counterparts. Conversely, adaptation can be encoded in larger-scale soft-robotic devices but remains elusive to transfer to the colloidal scale.

Hydrodynamics of flagellated microswimmers near free-slip interfaces [PDF]
, 2016 The hydrodynamics of a flagellated microorganism is investigated when swimming close to a planar free-slip surface by means of numerical solu- tions of the Stokes equations obtained via a Boundary Element Method.
