Au nanoparticles (NPs) of various sizes were synthesized by controlling the NP growth process. When the ratio of the HAuCl4 and NaBH4 solution concentrations was controlled, the experimental results showed that the average Au NP size decreased as the HAuCl4 concentration of the seed solution increas...
