Raman signal enhancements in excess of 10 7 can be achieved at near‐infrared wavelengths when mid‐nanometer sized gold particles self‐organize into close‐packed planar arrays. These substrates generate stable surface‐enhanced Raman scattering which changes dramatically as a function of periodic structure and excitation wavelength.
