Drops of nanoparticles self-stir and communicate
A single drop with active nanoparticles that collectively organize as well as several drops that communicate to coordinate their flow patterns.

Drops of nanoparticles self-stir and communicate

Researchers at the Max Planck Institute for Intelligent Systems have discovered a new mechanism of self-organization of active matter. When photochemically active nanoparticles are enclosed at high density within a drop and are exposed to UV light, a self-organized flow pattern emerges by spontaneous symmetry breaking. Furthermore, each drop communicates with neighbouring drops by exchanging chemicals, and coordination of their internal flows occurs – even when far apart.
