Bacterial contamination of biological channels, catheters or water resources is a major threat
to public health, which can be amplified by the ability of bacteria to swim upstream. The …

Despite mounting evidence that the same gradients, which active colloids use for swimming,
induce important cross-interactions (phoretic interactions), they are still ignored in most …

Swimming at the microscale has recently garnered substantial attention due to the
fundamental biological significance of swimming microorganisms and the wide range of …

The ability of microswimmers to deploy optimal propulsion strategies is of paramount
importance for their locomotory performance and survival at low Reynolds numbers …

We demonstrate that active carpets of bacteria or self-propelled colloids generate coherent
flows towards the substrate, and propose that these currents provide efficient pathways to …

The hydrodynamic flow field generated by self-propelled active particles and swimming
microorganisms is strongly altered by the presence of nearby boundaries in a viscous flow …

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

Self-propelled particles such as bacteria or algae swimming through a fluid are non-
equilibrium systems where particle motility breaks microscopic detailed balance, often …

Several recent experiments investigate the orientational and transport behavior of self-
driven bacteria and colloidal particles in nematic liquid crystals. Correspondingly, we study …

The interaction between nano-or micro-sized particles and cell membranes is of crucial
importance in many biological and biomedical applications such as drug and gene delivery …
