When Shear Cannot Break the Cluster: Off-Center Dipoles Under Flow
Move a magnetic particle’s dipole sideways and its clusters stop coming apart under shear. Our Brownian dynamics study maps where flow wins, where magnetism wins, and where the two trade places.
Moving the Magnet Off-Center: Designing What a Colloid Builds
Group member Jonathan Victoria-Camacho shows that shifting a magnetic particle's dipole away from its center changes which structures it assembles into — loops, worms, chains, and more.
Sensory Delay as a Feature: Janus Microswimmers That Adapt to Light and Chemistry
New Janus microswimmers self-regulate propulsion speed in response to light and dissolved chemicals. A built-in sensory delay makes their localization sharper, not slower.
