Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

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 …

Self-propelled particles, both biological and synthetic, are stably trapped by walls and
develop high concentration peaks over bounding surfaces. In swimming bacteria, like E. coli …

Bacteria are often discussed as active colloids, self-propelled organisms whose collective
motion can be studied in the context of non-equilibrium statistical mechanics. In such …

Using lattice Boltzmann simulations we study the hydrodynamics of an active spherical
particle near a no-slip wall. We develop a computational model for an active Janus particle …

Swimming bacteria can be trapped for prolonged times at the surface of an impenetrable
boundary. The subsequent surface confined motility is found to be very sensitive to the …

We study different types of microswimmers moving in channels with varying cross section
and thereby interacting hydrodynamically with the channel walls. Starting from the …

The hydrodynamic flow field generated by self-propelled active particles and swimming
microorganisms is strongly altered by the presence of nearby boundaries in a viscous flow …

The near-surface locomotion of microswimmers under the action of background flows has
been studied extensively, whereas the intervening effects of complex surface properties …

Cellular motility is a key function guiding microbial adhesion to interfaces, which is the first
step in the formation of biofilms. The close association of biofilms and bioremediation has …
