| Abstract: Highly ordered polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) honeycomb-patterned film was prepared by a static breath figure method, which was used as a template for the preparation of metal particles array. Honeycomb-like Ag nanoparticles array film was prepared with this polymer pattern through a photochemical reduction route. The SERS performance of this Ag nanoparticle array film was investigated with rhodamine 6G (R6G) as model molecule, which provides enhancement factors (EF) as high as 1.31×109. In addition, the substrate shows a lower limit of detection to 10-10 mol·L-1 for R6G and favorable uniformity through SERS mapping-scan spectra. The SERS signals collected at 120 points over a 30 μm×30 μm area present relative standard deviation of~12%. |
