Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

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 …

We review recent experimental, numerical, and analytical results on active suspensions of
self-propelled colloidal beads moving in (quasi-) two dimensions. Active colloids form part of …

In this Letter, we explore experimentally the phase behavior of a dense active suspension of
self-propelled colloids. In addition to a solidlike and gaslike phase observed for high and …

In this review article, we focus on collective motion in externally driven colloidal
suspensions, as well as how these collective effects can be harnessed for use in microfluidic …

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 …

Active particles such as swimming bacteria or self-propelled colloids spontaneously self-
organize into large-scale dynamic structures. The emergence of these collective states from …

Active colloids constitute a novel class of materials composed of colloidal-scale particles
locally converting chemical energy into motility, mimicking micro-organisms. Evolving far …

Active particles, such as swimming bacteria or self-propelled colloids, spontaneously
assemble into large-scale dynamic structures. Geometric boundaries often enforce different …

We review recent work on active colloids or swimmers, such as self-propelled
microorganisms, phoretic colloidal particles, and artificial micro-robotic systems, moving in …
