Conspectus Microorganisms use chemotaxis, regulated by internal complex chemical
pathways, to swim along chemical gradients to find better living conditions. Artificial …

Micromotors, which can be moved at a micron scale, have special functions and can perform
microscopic tasks. They have a wide range of applications in various fields with the …

Amphiphilic Janus particles feature the combination of two different functional materials in
one single colloid, as well as the possibility of self‐assembly at interfaces into complex …

Because they consume energy to drive their motion, systems of active colloids are
intrinsically out of equilibrium. In past decades, a variety of intriguing dynamic patterns have …

Mixtures of active and passive colloids show an intriguing dynamics of self-assembling,
which is driven by the active component. Self-phoretic active colloids generate sinks in a …

The collective behavior of chemically propelled sphere-dimer motors made from linked
catalytic and noncatalytic spheres in a quasi-two-dimensional confined geometry is studied …

The dynamics and stability of a swarm of microswimmers is examined here using a
thermodynamically compliant microswimmer model. The theory presented in this work is a …

Collective motion in nonequilibrium steady state suspensions of self-propelled Janus motors
driven by chemical reactions can arise due to interactions coming from direct intermolecular …

The propulsion of active particles by self-diffusiophoresis is driven by asymmetric catalytic
reactions on the particle surface that generate a mechanochemical coupling between the …

A survey is provided of a variety of problems where a passive or an active drop experiences
directed motion consequence of the action of an external or internal agent or a combination …
