Inspired by natural mobile microorganisms, researchers have developed micro/nanomotors
(MNMs) that can autonomously move by transducing different kinds of energies into kinetic …

Over the past 15 years, the field of microrobotics has exploded with many research groups
from around the globe contributing to numerous innovations that have led to exciting new …

Medical micro/nanorobots have received tremendous attention over the past decades owing
to their potential to be navigated into hard-to-reach tissues for a number of biomedical …

Active colloids use energy input at the particle level to propel persistent motion and direct
dynamic assemblies. We consider three types of colloids animated by chemical reactions …

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 …

Conspectus Engines and motors are everywhere in the modern world, but it is a challenge to
make them work if they are very small. On the micron length scale, inertial forces are weak …

Chemically powered nano-and micromotors are microscopic devices that convert chemical
energy into motion. Interest in these motors has grown over the past 20 years because they …

Chiral active particles (CAPs) are self-propelling particles that break time-reversal symmetry
by orbiting or spinning, leading to intriguing behaviors. Here, we examined the dynamics of …

Steering micromotors is important for using them in practical applications and as model
systems for active matter. This functionality often requires magnetic materials in the …

Synthetic active colloids that harvest energy stored in the environment and swim
autonomously are a popular model system for active matter. This emerging field of research …
