Optimal Control of Slender Microswimmers [PDF]
, 2017 We discuss a reduced model to compute the motion of slender swimmerswhich propel themselves by changing the curvature of their body. Our approach isbased on the use of Resistive Force Theory for the evaluation of the viscous forcesand torques exerted by the surrounding fluid, and on discretizing the kinematicsof the swimmer by representing its body ...

Microswimmers Knead Nematics into Cholesterics
Physical Review LettersThe hydrodynamic stresses created by active particles can destabilise orientational order present in the system. This is manifested, for example, by the appearance of a bend instability in active nematics or in quasi-2-dimensional living liquid crystals consisting of swimming bacteria in thin nematic films.

From 0D to 3D liquid crystal elastomers architectures: Fabrications and applications
Responsive Materials, Volume 4, Issue 2, May 2026.This review presents a dimension‐oriented overview of liquid crystal elastomers (LCEs), highlighting their molecular alignment, fabrication strategies, and programmable deformations from 0D particles to 3D architectures. Emphasis is placed on how dimensionality guides design principles, enables diverse actuation modes, and bridges fundamental ...

Run-and-tumble motion of ellipsoidal microswimmers [PDF]
Physical Review ResearchA hallmark of bacteria is their so-called “run-and-tumble” motion and its variants, consisting of a sequence of linear directed “runs” and distinct rotation events that constantly alternate due to biochemical feedback.

New Journal of Physics, 2019 This paper studies the influence of orienting external fields on pattern formation, particularly mesoscale turbulence, in microswimmer suspensions. To this end, we apply a hydrodynamic theory that can be derived from a microscopic microswimmer model ...

3D steerable, acoustically powered microswimmers for single-particle manipulation
Science Advances, 2019 Trapped bubbles make for fast and controllable microswimmers that can push or pull living cells in crowded microenvironments. The ability to precisely maneuver micro/nano objects in fluids in a contactless, biocompatible manner can enable innovative ...

Collision of microswimmers in a viscous fluid
Physical Review E, 2013 We investigate the effects of boundary conditions on the surface of self-propelled spherical swimmers moving in a viscous fluid with a low Reynolds number. We first show that collisions between the swimmers are impossible under the commonly used no-slip conditions.
