Gold nanorod surface preparation for enhanced EC-SERS: a comparison of two electrochemical CTAB removal protocols
Gold nanorods (AuNRs) present a promising alternative to silver nanoparticles (AgNPs) for surface-enhanced Raman spectroscopy (SERS) applications due to their improved biocompatibility, chemical stability, and tunable optical properties. However, the cetyltrimethylammonium bromide (CTAB) surfactant typically required f...
