The concentration of the plating solution enables control over the fine‐tuning of fractal patterns and also drastically affects the crystal growth of Ag/Au core–shell roughened nanoparticles through diffusion‐limited aggregation. At low concentrations there are more open spaces in the well‐ramified fractal pattern than at higher concentrations, and the whisker‐linked nanoparticles align almost one‐by‐one (see transmission electron micrograph).
