关于1-5nm AuNPs的制备
|
|
刚刚接触小尺寸的AuNPs的制备,参考文献的步骤合成(如下),在使用之前一定需要放置两个周吗?放置的这两个周有什么用?这个时间对于AuNPs有什么影响?谢谢大家!! Preparation of colloidal gold nanoparticles (GNPs). A THPC gold solution composed of 1–5 nm Au colloid was prepared as described by Duff et al.17 To 180 mL of ultrapure water was added 1.2 mL of 1MNaOH and 4mL of 1.2mMTHPC solution (prepared by adding 48 mL of 80% THPC in water to 4 mL of ultrapure water). Then, 6.75 mL of 25 mM aqueous chloroauric acid was added quickly to the mixture, aer which the solution immediately changed from colorless to a medium brown color. This gold seed solution should be stored at 4 C for at least 2 weeks before use. ![]() |
