Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation
Advanced Materials Technologies, Volume 11, Issue 6, 18 March 2026.This work introduces magnetically actuated microswimmers to dynamically reconfigure fluid flow within a single microfluidic device. Multiple homogeneous microswimmers are independently controlled by an external magnetic field to perform translational and rotational motions, thereby inducing real‐time flow manipulation.

A three-sphere microswimmer in a structured fluid
, 2018 We discuss the locomotion of a three-sphere microswimmer in a viscoelastic structured fluid characterized by typical length and time scales. We derive a general expression to link the average swimming velocity to the sphere mobilities.
