After decades of development, microrobots have exhibited great application potential in the
biomedical field, such as minimally invasive surgery, drug delivery, and bio‐sensing …

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 …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

Plasmonics offer unprecedented control over light and stimulate fundamental research and
engineering applications in solar energy. The surface plasmon resonance is responsible for …

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

Chemically powered micro‐and nanomotors are small devices that are self‐propelled by
catalytic reactions in fluids. Taking inspiration from biomotors, scientists are aiming to find …

This review summarizes theoretical progress in the field of active matter, placing it in the
context of recent experiments. This approach offers a unified framework for the mechanical …

Janus particles are colloidal particles with more than a single type of surface chemistry or
composition, ranging in size from hundreds of nanometers to a few micrometers. Like …

We study experimentally and numerically a (quasi-) two-dimensional colloidal suspension of
self-propelled spherical particles. The particles are carbon-coated Janus particles, which are …
