(A) Photograph of an experimental setup for scaled-up synthesis of Ag nanocubes. (B) SEM image of the Ag nanocubes (edge length: ~40 nm). The inset shows a TEM image of the same sample. (C) UV-vis spectra of the samples obtained by titrating the Ag nanocubes with different amounts of aqueous HAuCl4 solution. (D) TEM image of AuNCs (edge length: ~50 nm) with LSPR peaked at 780 nm.27
