Assembly of Gold Nanostar Cores within Silica Shell and Its Impact on Solid-state SERS and Non-enzymatic Catalytic Sensing

Abstract The paper elaborated on the morphology of multiple gold nanostar cores wrapped up in a single SiO2 shell and on the advantages of integrating many cores with sharp spikes into core-shell nanoparticles for SERS and catalytical sensing applications. In this study, AuNS-SiO2 core–shell nanoparticle assemblies were synthesized, incorporating multiple Au nanospheres (AuNSs) within thin silica shells. The synthesis relied on controlled nanoparticle aggregation without crosslinkers, providing new insights into assembly mechanisms. Differential centrifugation effectively separated assembled core–shell structures from single-core counterparts. Comprehensive TEM and EDX analyses confirmed the formation of multi-core nanostructures encapsulated in silica. Optical characterization revealed, besides the primary absorption peak in UV–vis–NIR spectra, an additional red-shifted absorption band, attributed to plasmonic coupling between closely packed AuNSs in the assemblies. These unique optical signatures directly correlate with surface-enhanced Raman scattering (SERS) activity. Enhanced SERS signals were rationalized by the capacitive electromagnetic field enhancement mechanism operating within nanoscale gaps and junctions among AuNSs. Overall, this work demonstrates a simple synthesis strategy for plasmonic nano-assemblies and establishes their potential in SERS-based sensing and electrochemical applications.
