Microscopic active droplets are able to swim autonomously in viscous flows. This puzzling
feature stems from solute exchanges with the surrounding fluid via surface reactions or their …

Self-propelled droplets are a class of active matter systems composed of one fluid dispersed
in another immiscible fluid. Despite the inherent spherical symmetry in the initial droplet …

The fluid dynamics of microswimmers has received attention from the fields of microbiology,
microrobotics, and active matter. Microorganisms have evolved organelles termed cilia for …

Microbes thrive in diverse porous environments—from soil and riverbeds to human lungs
and cancer tissues—spanning multiple scales and conditions. Short-to long-term …

Background Obtaining functional sperm cells is the first step to treat infertility. With the ever‐
increasing trend in male infertility, clinicians require access to effective solutions that are …

In this review, we provide a theoretical introduction to Jeffery's equations for the orientation
dynamics of an axisymmetric object in a flow at low Reynolds number, and review recent …

Self-propulsion of chemically active droplets and phoretic disks has been studied widely;
however, most research overlooks the influence of disk shape on swimming dynamics …

Living organisms routinely navigate their surroundings in search of better conditions, more
food, or to avoid predators. Typically, animals do so by integrating sensory cues from the …

Typical bodily and environmental fluids encountered by biological swimmers consist of
dissolved macromolecules such as proteins or polymers, rendering them even non …

The motion of biological swimmers in typical bodily fluids is modelled using a system of
micellar solubilization driven active droplets in a viscoelastic polymeric solution. The …
