A silver coating takes the lead in the SERS enhancement contest for nanorod supercrystals. On page 477, A. Guerrero‐Martínez, L. M. Liz‐Marzán, and co‐workers determine that supercrystals based on standing core–shell gold–silver nanorods stabilized by gemini surfactants are the SERS champions, knocking out their gold nanorod supercrystal counterparts. After a tough competition, silver substrates show a perfect combination of high optical activity and large homogeneous sensing area that will be difficult to defeat.
