Summary: A facile and green synthesis strategy was used to prepare a uniform three-dimensional (3D) nanostructure as surface-enhanced Raman scattering (SERS) sensors by decorating Ag nanoparticles (AgNPs) on TiO2 nanorod arrays. The AgNPs were distributed uniformly on the surface of TiO2 nanorods, as confirmed by XPS, SEM, and TEM analyses. The 3D hybrid substrate exhibited sensitive SERS signals and excellent spatial uniformity. The results also demonstrated the promising potential of the two-step synthesis strategy for preparing 3D hybrid nanostructure substrates for SERS.

Summary: EC-SOERS is a new phenomenon that enhances the Raman signal during the oxidation of a metal surface. Studies show that carbonyl and carboxyl groups are necessary to observe this phenomenon, with a delocated charge being important factor. Evaluating the enhancement factors for different molecules with highly delocated charge and a carboxyl group sheds more light on the interaction of molecules with the electrochemically generated SOERS substrates.
