Summary
Magnetic colloidal suspensions energized by alternating magnetic fields self-assemble into dynamic asters. These asters can capture and move microparticles, paving the way for self-assembled microrobots.
Area of Science:
- Soft matter physics
- Materials science
- Colloidal science
Background:
- Self-assembled materials require energy input to maintain non-equilibrium states for complex structures and functions.
- Understanding dynamic self-assembly is key to developing advanced functional materials.
