Infertility is a growing global health issue with far-reaching socioeconomic implications. A
downward trend in male fertility highlights the acute need for affordable and accessible …

In mammals, the architecture and physiology of the oviduct are very complex, and one long-
lasting intriguing question is how spermatozoa are transported from the sperm reservoir in …

One of the principal mechanisms by which surfaces and interfaces affect microbial life is by
perturbing the hydrodynamic flows generated by swimming. By summing a recursive series …

Swimming microorganisms often experience complex environments in their natural habitat.
The same is true for microswimmers in envisioned biomedical applications. The simple …

Microorganisms, such as bacteria and microalgae, often live in habitats consisting of a liquid
phase and a plethora of interfaces. The precise ways in which these motile microbes behave …

In the current study, the lattice Boltzmann method was used to explore the motion of an
elongated microswimmer in a horizontal channel with finite fluid inertia. By employing an …

The near-surface locomotion of microswimmers under the action of background flows has
been studied extensively, whereas the intervening effects of complex surface properties …

Active particles in diverse circumstances encounter confined channels with asymmetric
bounding walls. In the present work, employing the squirmer model, we analyze the …

Immotile and rare sperm isolation from a complex cell background is an essential process
for infertility treatment. The traditional sperm collection process from a biopsy sample …

The effect of shape asymmetry of microswimmers on their adsorption capacity at confining
channel walls is studied by a simple dumbbell model. For a shape polarity of a forward …
