Engineering Morphologies of Metal‐Based Colloidal Assemblies via Colloid Jamming at Liquid–Liquid Interfaces

NPs). Furthermore, it is demonstrated that the morphology of assemblies can be engineered via tuning MS NPs concentration under coordination regulation. With interfacial jamming, core-shell or homogeneously distributed binary colloidal assemblies are constructed. These findings highlight the importance of coordination interactions and concentration in shaping colloidal assemblies during evaporation-driven self-assembly in surfactant-stabilized microdroplets. This insight provides a foundation for designing functional materials with controlled architectures for applications in catalysis, plasmonics, and porous materials.
