A SERS ultradetection platform assembled from a commercially available PEG/PS graft copolymer and gold ions (see image) is shown to be optically and chemically stable, highly reproducible, and scalable. The tremendous simplicity of fabrication and low cost could make these materials a valuable tool for many potential users with no prior knowledge or experience in SERS‐active nanocomposite materials.
