Notes: A SERS substrate based on KI-modified AgNPs was developed to enable efficient identification of trace anthraquinone dyes in silk artifacts. SERS reference fingerprint spectra were established for five representative anthraquinone natural dyes: dyer’s madder (Rubia tinctorum), Indian madder (Rubia cordifolia), Japanese madder (Rubia argyi), lac insect (Kerria lacca) and cochineal (Dactylopius coccus). https://doi.org/10.1016/j.talanta.2025.129218
