ABSTRACT This study presents a robust and practical methodology for quantifying the Surface‐Enhanced Raman Spectroscopy (SERS) Enhancement Factor (EF) on both colloidal solid substrates. SERS, powerful technique enhancing signals of analytes near plasmonic surfaces, has found extensive applications in fields such as biomedicine materials science. However, inconsistencies EF measurement methods have hindered cross‐comparisons between different SERS work addresses these challenges by providing standardized protocol determination wide variety substrates composed gold silver nanoparticles, well nanostructured surfaces. Using p‐mercaptobenzoic acid (p‐MBA) model non‐resonant probe, approach accounts key variables including substrate geometry, sampling volume, inhomogeneity. reliable reproducible method offers framework researchers to assess performance with simple instruments techniques that should be easily available spectroscopy laboratory.

The seed-mediated growth involving cetyltrimethylammonium chloride (CTAC), silver trifluoroacetate (CF3COOAg), ascorbic acid (H2Asc), and Ag seeds covered by poly(vinylpyrrolidone) (PVP) in aqueous medium is a robust route to nanocubes with tunable sizes. However, mechanistic details such as changes the surface remain elusive. Herein, we address this issue leveraging high sensitivity water compatibility of surface-enhanced Raman scattering (SERS). Our results reveal that addition CTAC ligand exchange between PVP further introduction CF3COOAg leads deposition AgCl on seeds. H2Asc subsequently introduced increases electron density due transfer, manifested rapid pronounced enhancement SERS signals from CTA+. electrons also enable reduction directly transform contact into atoms enlarge nanocubes.
