A short synthesis route to silica-encapsulated nanoparticles coated with a self-assembled monolayer (SAM) is presented. The organic molecules within the SAM contain a SiO2 precursor to render the surface vitreophilic. Due to the high mechanical and chemical stability of a glass shell, such particles can be used as probes in targeted research with surface-enhanced Raman scattering as the read-out method.
