We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

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

The development of novel drug delivery systems, which are revolutionizing modern
medicine, is benefiting from studies on microorganisms' swimming. In this paper we consider …

The Green's function plays an important role in many areas of physical sciences and is a
prime tool for solving diverse hydrodynamic equations in the linear regime. In the present …

A colloidal motor driven by surface tension forces is theoretically designed by encapsulating
an active Janus particle in a liquid drop which is immiscible in the suspending medium. The …

We theoretically and computationally study the low-Reynolds-number hydrodynamics of a
linear active microswimmer surfing on a compressible thin fluid layer characterized by an …

Numerous experiments and theoretical calculations have shown that cylindrical vesicles can
undergo a pearling instability similar to the Rayleigh–Plateau instability of a liquid jet when …

Microorganisms navigate through fluid, often confined by complex environments, to survive
and sustain life. Inspired by this fact, we consider a model system and seek to understand …

From bacteria and sperm cells to artificial microrobots, self-propelled microscopic objects at
low Reynolds numbers often perceive fluctuating mechanical and chemical stimuli and …

Artificial and living microswimmers encounter a large variety of geometric confinements and
surfaces in the biological world. Here, we study the low-Reynolds-number dynamics of a …
