Well‐defined nanovoid and metal‐ nanocap arrays are fabricated on flexible polymer substrates with controlled sizes and morphologies, via trapping of inorganic particles at a polymer‐film surface. The proposed method provides a platform to create an effective SERS substrate, for use in devices such as chemical and biomolecular sensors.
