We improve the reliability of the SERS sensor by integrating intensity based self-referencing mechanism. The self-referenced mechanism was realized by sandwiching a monolayer of 4-Amino Thiophenol (4-ATP) between Ag nanoparticles and Ag nano-sculptured thin film (nSTF). The sensor performance is independent of the integration time of the detector. Intensity-based self-referencing mechanism proposes to resolve a long-lasting issue of SERS-based quantitative detection with high reliability. SERS sensor also possesses an excellent uniformity.
