Y.‐J. Oh and K.‐H. Jeong report the enhancement of surface‐enhanced Raman scattering (SERS) using glass nanopillars surrounded by nanogap‐rich silver nanoislands at wafer level. On page 2234 , they explain how high‐density hot spots are generated by increasing the number of nanogap‐rich nanoislands within a detection volume. The SERS substrate shows high enhancement factor with excellent signal uniformity. This novel substrate enables the label‐free detection of aqueous DNA base molecules at nanomolar level.
