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 …

Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

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

We review theoretical models of individual motility as well as collective dynamics and
pattern formation of active particles. We focus on simple models of active dynamics with a …

Active particles contain internal degrees of freedom with the ability to take in and dissipate
energy and, in the process, execute systematic movement. Examples include all living …

Cell motility in viscous fluids is ubiquitous and affects many biological processes, including
reproduction, infection and the marine life ecosystem. Here we review the biophysical and …

The swimming trajectories of self-propelled organisms or synthetic devices in a viscous fluid
can be altered by hydrodynamic interactions with nearby boundaries. We explore a …

This review describes recent developments in self-propelling nano-and micro-scale
swimming devices. The ability of these devices to transport nano-scale components in a …

The creation of synthetic systems that emulate the defining properties of living matter, such
as motility, gradient-sensing, signaling, and replication, is a grand challenge of biomimetics …

The use of swarms of nanobots to perform seemingly miraculous tasks is a common trope in
the annals of science fiction. 1 Although several of these remarkable feats are still very much …
