Emergent Motility of Self‐Organized Particle‐Giant Unilamellar Vesicle Assembly
Advanced Materials, EarlyView.Giant unilamellar vesicles (GUVs), when combined with silica particles under alternating electric fields, spontaneously self‐assemble into motile structures. Asymmetric particle decoration induces fluid flows that propel the assemblies, enabling persistent motion and reversible control.
