The fabrication of 3D gold nanoparticle layer was processed by O.R.C. (oxidation and reduction cycle) and detection of protein via dual signal model (Raman Spectroscopy and Electrochemical Study) . In this study, it is demonstrated that the gold electrode with gold nanopaticle layers may serve as excellent SERS substrates in chemical and biomedical detection. In this work, we performed polishing technology to optimize the O.R.C. process and demonstrated the important correlation between polishing technology and nanoparticle layer substrates in Raman signal mapping mode. Overall, results indicated that the method with polishing treatment for dual signal model led to signal improvement and can be potentially used to develop environmental pollution and biomedical sensing platform.
