Self-assembly of polymeric micelles into complex but regular superstructures based on highly controllable core-core fusion between the micelles.

Herein, we report a facile but highly controllable method to induce core-core fusion for not only spherical but also worm-like polymeric micelles, leading to various complex but regular superstructures including "random worm-like co-micelles", "block worm-like co-micelles" and octopus-like superparticles.
