Schematic structures and representative transmission electron micrographs (TEM) of the SERS-based Au NPs (NBT@Au NPs) of 68.3 nm in average diameters. Scale bars, 100 nm. The reporter molecule 4-NBT was incorporated into Au NPs or Au GERTs. Image shown is representative of n = 3 independent replicates of experiments with similar results.
