Since its discovery in the 1970s, surface-enhanced Raman spectroscopy (SERS) has been used to boost the signal obtained from molecules sitting on rough or finely structured metal surfaces, typically made of either silver or gold. Now, Gokhan Demirel of Gazi University, Hakan Usta of Abdullah Gül University, Antonio Facchetti and George C. Schatz of Northwestern University, and coworkers have achieved signal enhancement using a . . .
