The functionalization of a gold surface with 3-aminopropyl-triethoxysilane (APTES) enhances the performance of fiber optic-based plasmonic sensors. Using the aqueous phase deposition (APD) method, APTES concentrations of 1–4% were tested. FTIR analysis showed increased amine (-NH₂) absorption with ammonium ions interacting electrostatically …
