  • Characterization of optical properties and orientation dependence.

    • Main Results:

    • Stable 3D nanoparticle clusters were successfully assembled.
    • Optical properties were found to be sensitive or independent of cluster orientation based on geometry and particle number.
    • Tetrahedral and icosahedral clusters demonstrated potential as optical kernels for metafluids.

    Conclusions:

    • The developed method enables the creation of versatile 3D nanoparticle structures.
    • These 3D clusters can impart metamaterial properties to disordered media like liquids and plastics.
    • The orientation-independent properties of certain clusters are advantageous for metafluid applications.
