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

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 …

A sperm-driven micromotor is presented as a targeted drug delivery system, which is
appealing to potentially treat diseases in the female reproductive tract. This system is …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

INTRODUCTION Microtubules are key components of the eukaryotic cytoskeleton. Although
they are involved in a wide variety of functions, microtubules are structurally highly similar …

Many microorganisms, with phytoplankton and zooplankton as prominent examples, display
phototactic behaviour, that is, the ability to perform directed motion within a light gradient …

Motile cilia are miniature, propeller-like extensions, emanating from many cell types across
the body. Their coordinated beating generates a directional fluid flow, which is essential 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 …

Artificial microswimmers that can replicate the complex behavior of active matter are often
designed to mimic the self-propulsion of microscopic living organisms. However, compared …

Acoustic actuation of bioinspired microswimmers is experimentally demonstrated.
Microswimmers are fabricated in situ in a microchannel. Upon acoustic excitation, the …
