Conspectus Catalytic Janus colloids produce rapid motion in fluids by decomposing
dissolved fuel. There is great potential to exploit these “autonomous chemical swimmers” in …

Fluid dynamics plays a crucial role in many cellular processes, including the locomotion of
cells such as bacteria and spermatozoa. These organisms possess flagella, slender …

We study the two-dimensional motion of a self-propelling asymmetric bent rod. By employing
slender body theory and the Lorentz reciprocal theorem, we determine particle trajectories …

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 …

We study synchronization in bulk suspensions of spherical microswimmers with chiral
trajectories using large scale numerics. The model is generic. It corresponds to the lowest …

Diffusiophoresis involves the movement of colloidal-scale entities in response to
concentration gradients of a solute. It is broadly categorized into two types: passive and …

The development of top-down active control over bottom-up colloidal assembly processes
has the potential to produce materials, surfaces, and objects with applications in a wide …

The motion of an autophoretic spherical particle in a simple fluid is analyzed. This motion is
powered by a chemical species which is absorbed or emitted by the particle and which …

Phoretic particles exploit local self-generated physico-chemical gradients to achieve self-
propulsion at the micron scale. The collective dynamics of a large number of such particles …

Many microorganisms take a chiral path while swimming in an ambient fluid. In this paper
we study the combined behavior of two chiral swimmers using the well-known squirmer …
