Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from
their surroundings. Here, we review the numerical and theoretical modeling of active …

Medical micro/nanorobots have received tremendous attention over the past decades owing
to their potential to be navigated into hard-to-reach tissues for a number of biomedical …

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 …

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 …

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 …

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of
critical importance in many biological processes such as fertilization, infection, and biofilm …

The collective mobility of active matter (self-propelled objects that transduce energy into
mechanical work to drive their motion, most commonly through fluids) constitutes a new …

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

We experimentally investigate active motion of spherical Janus colloidal particles in a
viscoelastic fluid. Self-propulsion is achieved by a local concentration gradient of a critical …

Abstract Systems made by particles in viscoelastic liquids are ubiquitous in a variety of
industrial and biological applications. Much work has been done in the last half-century in …
