[求助] 金簇浓度的计算

请问合成的金簇的浓度应该怎么计算啊?最终形成的金簇的物质的量是不是与开始时加入的HAuCl4的物质的量一样啊?

If there is enough reductant during the synthesis, one can assume all Au is reduced and form AuNCs. In case you know the atomic composition of these AuNCs, e.g., Au8 or Au 25, then you can estimate the molar concentration of these particles. Or else, you can only use the weight concentration, such as XX µg/ml, to denote the concentration of AuNCs.

我现在就是按照你发在small上的One-Pot Synthesis of Near-Infrared Fluorescent Gold Clusters for Cellular Fluorescence Lifetime Imaging
里的方法合成的金簇(DHLA--AuNCs),想知道金簇的浓度以继续后面的工作,文中没有提到,可否告知呢?您在前面提到的根据根据金簇的原子组成来估算金簇的浓度(文章中提到了金簇的主要组成可能是是Au22),可否指明估算的原理或方法呢?不甚感激啊!!
