Facile fabrication of nanoporous gold films for surface plasmon resonance (SPR) sensing and SPR-based SERS
Chen Chen, Ziwei Liu, Chen Cai, Zhi‐mei Qi
Abstract
NPG films with controllable thickness and smaller pores are prepared by the sputtering-low-temperature dealloying process, and the spatial overlap of the SPP and the adsorbed analyte molecules offers the NPG film significant SERS enhancement.
