Abstract

Surface Enhanced Spectroscopy-Active Composite Nanoparticles (SACN) comprising: core/shell nanoparticles comprising nanoparticle cores covered with shells, wherein the cores and the shells may comprise the same or different materials; at least one Raman-active reporter molecule associated with said core/shell nanoparticle; and an SiO2 encapsulant which encapsulates the core/shell nanoparticle and the at least one Raman-active reporter molecule, are described.
