On page OP 175 , U. Steiner and co‐workers destabilise polymer trilayer films using an electric field to generate separated micrometre‐sized core‐shell pillars, which are further modified by selective polymer dissolution to yield polymer core columns surrounded by a rim and micro‐volcano rim structures. When coated with gold and decorated with Raman active probes, all three structure types give rise to substantial enhancement in surface‐enhanced Raman scattering (SERS). Since this SERS enhancement arises from each of the isolated structures in the array, these surface patterns are an ideal platform for multiplexed SERS detection.
