(A) Schematic showing the synthesis of a hollow silica/vinyl-silica sphere with a hole in the wall through site-selected deposition by templating with the Au-PS Janus particle. (B, D) TEM images of Au-PS particles containing (B) 50- and (D) 100-nm Au nanoparticles. (C, E) SEM images of the as-obtained hollow silica spheres by templating with Au-PS Janus particles in (B, D), respectively. The insets show TEM images of the corresponding samples.
