Swimming droplets are artificial microswimmers based on liquid droplets that show self-
propelled motion when immersed in a second liquid. These systems are of tremendous …

This review describes the current knowledge and applications of pulsatile flow in microfluidic
systems. Elements of fluid dynamics at low Reynolds number are first described in the …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

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 …

We formulate the theory for steering an active particle with optimal travel time between two
locations and apply it to the Mexican hat potential without brim. For small heights the particle …

We study the dynamics of a prolate spheroidal microswimmer in Poiseuille flow for different
flow geometries. When moving between two parallel plates or in a cylindrical microchannel …

Directed motility enables swimming microbes to navigate their environment for resources via
chemo-, photo-, and magneto-taxis. However, directed motility competes with fluid flow in …

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 …

Interactions between microorganisms and their complex flowing environments are essential
in many biological systems. We develop a model for microswimmer dynamics in non …

Trypanosoma brucei is responsible for lethal diseases in humans and cattle in Sub-Saharan
Africa. These extracellular parasites extravasate from the blood circulation into several …
