Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

Bacteria are among the oldest and most abundant species on Earth. Bacteria successfully
colonize diverse habitats and play a significant role in the oxygen, carbon, and nitrogen …

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 review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

Understanding how bacteria move close to surfaces is crucial for a broad range of microbial
processes including biofilm formation, bacterial dispersion, and pathogenic infections. We …

Flagellated bacteria exploiting helical propulsion are known to swim along circular
trajectories near surfaces. Fluid dynamics predicts this circular motion to be clockwise (CW) …

Microscopic swimmers, eg, chemotactic bacteria and cells, are capable of directed motion by
exerting a force on their environment. For asymmetric microswimmers, eg, bacteria …

The boundary behavior of axisymmetric microswimming squirmers is theoretically explored
within an inertialess Newtonian fluid for a no-slip interface and also a free surface in the …

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 …

Despite the mounting interest in synthetic active particles, too little is known about their
assembly into higher‐order clusters. Here, mixing bare silica particles with Janus particles …
