Micro‐and nanorobots have shown great potential for applications in various fields,
including minimally invasive surgery, targeted therapy, cell manipulation, environmental …

The past two decades have seen a remarkable progress in the development of synthetic
colloidal agents which are capable of creating directed motion in an unbiased environment …

Conventional photocatalytic micromotors are limited to the use of specific wavelengths of
light due to their narrow light absorption spectrum, which limits their effectiveness for …

Hematite microparticles are becoming increasingly important components in the soft matter
field. The remarkable combination of magnetic and photocatalytic properties that …

We study theoretically an active colloid whose polar axis of self-propulsion rotates to point
parallel (antiparallel) to an imposed chemical gradient. We show that the coupling of this …

The question of how “smart” active agents, like insects, microorganisms, or future colloidal
robots need to steer to optimally reach or discover a target, such as an odor source, food, or …

The growing interest in the design and fabrication of novel autonomous micro‐and
nanoparticles is motivated by the vast advances in their motion efficiency and their further …

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 …

We study the motion of active Janus colloids in an optical trap using experiments, theory and
numerical simulations. To achieve isotropic and harmonic confinement, we prototype …

Colloidal micromotors can autonomously propel due to their broken symmetry that leads to
unbalanced local mechanical forces. Most commonly, micromotors are synthesized to …
