This paper describes the fastest route to monodispersed silver nanocubes. By adding a trace amount of sodium sulfide (Na(2)S) or sodium hydrosulfide (NaHS) to the conventional polyol synthesis, the reaction time was significantly shortened from 16-26 hours to 3-8 minutes. By merely adjusting the reaction time, monodispersed silver nanocubes of 25-45 nm in edge length were rapidly and routinely produced on relatively large scales. These small nanocubes are of great interest for biomedical applications by way of generating gold nanocages with plasmon resonance peaks tunable to the near-infrared region through a galvanic replacement reaction.
本文描述了制备单分散银纳米立方体的最快途径。通过向传统的多元醇合成中添加痕量的硫化钠（Na₂S）或硫氢化钠（NaHS），反应时间从16 - 26小时显著缩短至3 - 8分钟。仅通过调整反应时间，就能在相对较大规模上快速且常规地制备出边长为25 - 45纳米的单分散银纳米立方体。这些小的纳米立方体对于生物医学应用具有极大的吸引力，因为通过电化学生成反应，可生成等离子体共振峰可调谐至近红外区域的金纳米笼。
