In active matter systems, individual constituents convert energy into non-conservative forces
or motion at the microscale, leading to morphological features and transport properties that …

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 …

INTRODUCTION Conventional nonequilibrium systems are composed of inanimate
components whose dynamics is powered by the external input of energy. For example, in a …

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 …

Biohybrid microrobots, composed of a living organism integrated with an artificial carrier,
offer great advantages for the miniaturization of devices with onboard actuation, sensing …

The mammalian female reproductive tract interacts with sperm in various ways in order to
facilitate sperm migration to the egg while impeding migrations of pathogens into the tract, to …

A major puzzle in biology is how mammalian sperm maintain the correct swimming direction
during various phases of the sexual reproduction process. Whilst chemotaxis may dominate …

Dense suspensions of swimming bacteria are known to exhibit collective behaviour arising
from the interplay of steric and hydrodynamic interactions. Unconfined suspensions exhibit …

Interactions between swimming cells and surfaces are essential to many microbiological
processes, from bacterial biofilm formation to human fertilization. However, despite their …
