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 …

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of
critical importance in many biological processes such as fertilization, infection, and biofilm …

We report the emergence of large zigzag bands in a population of reversibly actuated
magnetic rotors that behave as active shakers, namely squirmers that shake the fluid around …

Microscopic organisms must frequently swim through complex biofluids, including bacterial
biofilms and the mucus lining of the upper respiratory tract. Recently, there has been great …

In Newtonian fluids, microswimmers need to perform a non-reciprocal shape change to
move forward. However, this is no longer required in biological fluids with their viscoelastic …

We experimentally study the dynamics of active particles (APs) in a viscoelastic fluid under
various geometrical constraints such as flat walls, spherical obstacles and cylindrical …

We study the mechanically driven flows of non-Newtonian fluids in narrow and confined
configurations. Using the Lorentz reciprocal theorem, we derive a closed-form expression for …

The need for structuring on micrometer scales is abundant, for example, in view of phononic
applications. We here outline a novel approach based on the phenomenon of active …

We present a self-propelled axisymmetric low-Reynolds-number swimmer (force-and torque-
free) that, while unable to swim in a Newtonian fluid, propels itself in a non-Newtonian fluid …

The dynamics and stability of a swarm of microswimmers is examined here using a
thermodynamically compliant microswimmer model. The theory presented in this work is a …
