摘要

•SERS-based immunoassay was carried out using AgNP-decorated electrospun fibers as capture substrate.•SERS signal was greatly amplified by the generation of hot spots between AgNPs on fibers and AuNP-based SERS tag.•Fast and sensitive detection of PSA was possible due to the large surface area and porous structure of fibrous substrate.
