We report nanotags encapsulated in Au–Ag nanostructure that are active in surface-enhanced Raman scattering. The Au–Ag nanoshells are filled with Ag via citrate reduction, entrapping label molecules in the process. The nanotags can be used for quantitative SERS measurements with the label molecules as internal reference.
