摘要：

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).
