When Particles Synchronize and Swarm — A Tunable Colloidal Swarmalator
A new colloidal experiment lets researchers dial a single knob and switch between synchronized clusters, rotating aggregates, and dispersed phases — the first fully tunable swarmalator system in the lab.
What the Péclet Number Tells Us About Particle Transport
A single dimensionless ratio tells you whether a colloidal particle motion is shaped by flow or by random kicks of the surrounding solvent.
From Target to Particle: Inverse Design Comes to Colloidal Self-Assembly
Generative models, surrogate optimization, and reinforcement learning are flipping the colloidal self-assembly workflow from forward to reverse.
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.
Diffusiophoresis: When a Concentration Gradient Moves a Particle
A dissolved salt can push colloidal particles without any fluid flow. Diffusiophoresis explains the mechanism — and why it matters across soft matter.
