We review recent work on active colloids at interfaces, including self-propelled colloids that
move by generating a propulsive force, and driven colloids that move under external fields …

Colloidal particles can be adsorbed at fluid–fluid interfaces, a phenomenon frequently
observed in particle-stabilized foams, Pickering emulsions, and bijels. Particles adsorbed at …

Colloids often behave in a manner similar to their counterparts in molecular space and are
used as model systems to understand molecular behavior. Here, we study like-charged …

The behavior of Janus particles fabricated from core silica particles decorated with gold
nanoparticles on one hemisphere is studied at the air/water interface. An unexpected …

Janus nanoparticles could exhibit a higher interfacial activity and adsorb stronger to fluid
interfaces than homogeneous nanoparticles of similar sizes. However, little is known about …

Langmuir monolayers of silica/gold Janus particles with two different degrees of
amphiphilicity have been examined to study the significance of particle surface …

It has been shown both theoretically and experimentally that amphiphilic Janus particles are
the most effective solid surfactants to stabilize interfaces. In most cases, the Janus particles …

Tracking the three-dimensional rotation of colloidal particles is essential to elucidate many
open questions, eg concerning the contact interactions between particles under flow, or the …

In this article, we review both theoretical models and experimental results on the motion of
micro-and nano-particles that are close to a fluid interface or move in between two fluids …

Cellular uptake of nanoplastics is instrumental in their environmental accumulation and
transfer to humans through the food chain. Despite extensive studies using spherical plastic …
