Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation

open access: yesAdvanced Materials Technologies, EarlyView.
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.
