Particles adsorbed to fluid interfaces are ubiquitous in industry, nature or life. The wide
range of properties arising from the assembly of particles at fluid interface has stimulated an …

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 …

The motion of self-propelled tubular micro-and nanojets has so far been achieved by bubble
propulsion, eg, O2 bubbles formed by catalytic decomposition of H2O2, which renders future …

This review explores the intersection between two important fields of colloid and interface
science–that of active colloidal particles and of (passive) particles at fluid-fluid interfaces …

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 …

We apply laser light to induce the asymmetric heating of Janus colloids adsorbed at water-
oil interfaces and realize active micrometric “Marangoni surfers.” The coupling of …

The development of multifunctional and robust swimming microrobots working at the free air–
liquid interface has encountered challenge as new manipulation strategies are needed to …

One of the recent frontiers of nanotechnology research involves machines that operate at
nano-and microscales, also known as nano/micromotors. Their potential applications in …

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

Bacteria are important examples of active or self-propelled colloids. Because of their
directed motion, they accumulate near interfaces. There, they can become trapped and swim …
