Nanoelectrum across the Visible Spectrum: Tailored Ag-Au Alloy Nanoparticles with Glutathione-Enhanced Stability.

ABSTRACT: Nanoelectrum (Ag-Au alloy nanoparticles, Ag-Au NPs) combines the unique nanoscale characteristics of silver and gold into a single bimetallic system exhibiting synergistic properties distinct from those of individual metals. Despite their significant potential and enhanced performance in applications such as catalysis and surface-enhanced Raman spectroscopy (SERS), the use of Ag-Au NPs remains limited due to challenges in achieving controlled and reproducible synthesis. Here, we present surfactant-assisted and surfactant-free approaches for the synthesis of both hollow and solid Ag-Au NPs from AgNP seeds across a wide range of Ag to Au ratios and AgNP sizes. We highlight the synergistic role of Cl^- ions and reducing agents in controlling the extent of galvanic replacement and mi
