  bibo_abstract:
  - Three‐dimensional (3D) assemblies of gold nanoparticles (AuNPs) offer a rich platform
    for plasmonic coupling and near‐field engineering, yet their optical behavior
    is often complex due to structural disorder and fabrication‐induced variability.
    Here, we present a systematic optical investigation of large‐scale 3D AuNP assemblies
    fabricated via meniscus‐guided assembly, focusing on the reproducibility, spatial
    uniformity, and mode evolution of their plasmonic responses. Spatially‐resolved
    dark‐field scattering measurements reveal that high‐aspect‐ratio AuNP pillars
    exhibit uniform scattering spectra along their height and across different pillars,
    despite variations in geometry and structure. Electromagnetic simulations suggest
    that this robustness arises from a collective many‐particle plasmonic response
    that remains optically active despite structural perturbations. The corresponding
    near‐field and surface‐charge distributions remain spatially distributed under
    representative structural perturbations, consistent with volumetric averaging
    across the three‐dimensional assembly. Building on this robust platform, we introduce
    compositional modulation through a core–satellite architecture by incorporating
    smaller AuNPs. This yields a composition‐dependent spectral redistribution, including
    the emergence of an additional long‐wavelength spectral feature in the core–satellite
    assemblies. Wavelength‐dependent surface‐enhanced Raman scattering measurements
    reveal contrasting responses under 633 and 785 nm excitation, reflecting redistribution
    of local plasmonic coupling pathways. These results provide process‐enabled guidelines
    for using meniscus‐guided 3D‐nanoprinting to realize robust nanoparticle assemblies.@eng
