Remote plasmonic enhanced Raman spectroscopy (RPERS) is a Raman spectroscopy technique that enhances optical signal intensity without the need for metal contact by constructing tens of nm silica columnar structures on silver nanostructures. In this study, the chemical stability and robustness of RPERS substrates were verified for the application of RPERS to biosensing fields such as environmental monitoring and cellular measurements. Specifically, the light-enhancing properties of RPERS were evaluated by immersion in NaCl and NaBr solutions, which contain halogen molecules naturally present in biological experiments and in living organisms.
