A novel method for fabricating silver‐based SERS‐active substrates is reported by K. Rademann et al. on p. 1683. Long‐term stable (more than two years) silver ion‐exchanged metal‐oxide glasses conserve silver nanoparticles in the subsurface region. Etching the protective glass surface activates the substrate. When exposed to analyte molecules, a strong Raman enhancement can be recorded as a SERS spectrum. The picture shows adenine as a test molecule.
