Most swimming bacteria are capable of following gradients of nutrients, signaling molecules
and other environmental factors that affect bacterial physiology. This tactic behavior became …

Taxis orientation is common in microorganisms, and it provides feasible strategies to
operate active colloids as small‐scale robots. Collective taxes involve numerous units that …

Biological microswimmers navigate upstream of an external flow with trajectories ranging
from linear to spiralling and oscillatory. Such a rheotactic response primarily stems from the …

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 …

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 …

Rheotaxis and migration of cells in a flow field have been investigated intensively owing to
their importance in biology, physiology and engineering. In this study, first, we report our …

This article provides a review of the recent development of biomimicking behaviors in active
colloids. While the behavior of biological microswimmers is undoubtedly influenced by …

To survive in harsh environments, single-celled microorganisms autonomously respond to
external stimuli, such as light, heat, and flow. Here, we elucidate the flow response of …

Rheotaxis is a well-known phenomenon among microbial organisms and artificial active
colloids, wherein the swimmers respond to an imposed flow. We report the first experimental …

A key feature of many living systems, such as bacteria and eukaryotic cells, is their ability to
actively self-propel. Indeed, cellular motility underlies numerous critical biological …
