Modeling active colloids: From active brownian particles to hydrodynamic and chemical fields
Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from
their surroundings. Here, we review the numerical and theoretical modeling of active …

Phoretic self-propulsion
It is well-known that micro-and nanoparticles can move by phoretic effects in response to
externally imposed gradients of scalar quantities such as chemical concentration or electric …

Hydrodynamics determines collective motion and phase behavior of active colloids in quasi-two-dimensional confinement
We study the collective motion of confined spherical microswimmers such as active colloids
which we model by so-called squirmers. To simulate hydrodynamic flow fields including …

Tuned, driven, and active soft matter
AM Menzel - Physics reports, 2015 - Elsevier
One characteristic feature of soft matter systems is their strong response to external stimuli.
As a consequence they are comparatively easily driven out of their ground state and out of …

Swimming in complex fluids
We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …
