Thumbnail image of graphical abstract

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.
