Abstract
Herein we report the facile synthesis of freestanding silver dendrite (AgD)/graphene oxide (GO) composite membranes, and demonstrate their use as an efficient and robust substrate with large-area uniformity and good reproducibility for surface-enhanced Raman scattering (SERS) applications. The as-prepared composite membranes exhibit excellent sensitivity for detecting rhodamine 6G and 5,5′-dithiobis-(2-nitrobenzoic acid). The results suggest that AgD/GO nanocomposite membrane holds great promise as a high-performance SERS substrate for plasmonic sensing applications.
