SERS-Active Ag Decorated Polymer Nanorod Substrate Fabricated by the Combination of Photochemical Reduction and Nanoimprint Technology

Abstract

We demonstrated a cost-effective and simple method of fabricating Ag-decorated polymer nanorod (ADPN) array by the combination of fabricated by the combination of photochemical reduction and nanoimprint technology. Here, nanoimprint lithography is utilized to fabricate polymer nanorod array as the periodic temple. Subsequently, ADPNs array can be achieved via UV irradiating. The as-synthesized ADPNs array exhibited a remarkable SERS activity and Raman signal reproducibility to rhodamine 6G, a concentration down to 1011 M can be identified. Our results revealed that the ADPN array is a highly desirable candidate as the reliable enhancer for high performance SERS analysis.
