In this study, we investigate a novel two-step synthesis of Fe/SiO2/Au core/shell nanoparticles by aqueous reduction using sodium borohydride. The composition, morphology, and magnetic behavior were determined by X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, and room temperature vibrating sample magnetometry. We also demonstrate their application as surface-enhanced Raman substrates. We evaluate their performance as SERS active material using pyridine as a model compound. Core/sheel nanoparticles with optical and magnetic functionality offer broad opportunities for biomedical and SERS applications.
