In this study, multifunctional hybrid nanoparticles composed of iron platinum (FePt), silica (SiO 2 ), and gold nanoparticles (AuNPs) had been developed for surface-enhanced Raman scattering (SERS) application. Core-shell structure of SiO 2 and FePt nanoparticles (FePt@SiO 2 ) was fabricated through...
