描述
银纳米立方体
NanoSeedz™提供高质量的银纳米立方体，具体的产品参数请见下面。这些银纳米立方体是在溶液中用化学法合成的，颗粒纯度高达95%以上，样品经过消光光谱和电镜严格表征。我们致力于精确控制银纳米立方体的尺寸、形状和颗粒纯度，但不同合成批次间不可避免地会有细小的尺寸变化。

表面包覆分子：poly(vinylpyrrolidone) (PVP，分子量：55000)
分散溶剂：乙醇 (PVP，0.2 mg/mL) + 水，体积比1:1
流体动力直径：~130 nm和~180 nm
表面Zeta电位：-25 mV
银纳米立方体按下列方式提供。
| 平均边长(nm) | 数量(瓶) | 银的绝对质量(mg) | 价格(人民币) |
| 73.0 | 1 | 0.5 | 700 |
| 10 | 5 | 6300 | |
| 20 | 10 | 11200 | |
| 101.5 | 1 | 0.5 | 700 |
| 10 | 5 | 6300 | |
| 20 | 10 | 11200 |
建议把银纳米立方体保存在溶液中避光并置于4 °C的冰箱中。为了确保银纳米立方体均匀分散在溶液中，在使用前先超声1分钟，然后再轻微地涡旋振动，或手动摇晃溶液直至银纳米立方体沉淀均匀分散。
