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 ...

Shaping Function: Polymeric 3D Systems With Unconventional Geometries for Biomedical Applications
Small, Volume 22, Issue 33, 12 June 2026.Particle shape is a key design parameter governing biological interactions. Advances in fabrication enable precise control over anisotropy and compartmentalization, allowing modulation of cellular uptake, transport, and biodistribution, ultimately enhancing therapeutic performance. ABSTRACT Polymer geometry is a primary determinant of physical behavior

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.

Collective behaviour of model microswimmers [PDF]
, 2010 At small length scales, low velocities, and high viscosity, the effects of inertia on motion through fluid become insignificant and viscous forces dominate. Microswimmer propulsion, of necessity, is achieved through different means than that achieved by

Trypanosomes – versatile microswimmers
, 2016 Evolution has generated a plethora of flagellate microswimmers. They populate all natural waters, from the deep sea to the ponds in our neighbourhood. But flagellates also thrive in the bodies of higher organisms, where they mostly remain undetected, but

Propulsion of Planar V‐Shaped Microswimmers in a Conically Rotating Magnetic Field
Advanced Intelligent SystemsPlanar magnetic microswimmers bear great potential for in vivo biomedical applications as they can be mass‐produced at minimal costs using standard photolithography techniques. Therefore, it is central to understand how to control their motion.
