[交流] 【请教】有谁做过AU@SiO2?帮帮忙啊!

2ml*50nmAu Nps+10ml 异丙醇+0.15ml*30wt%氨水,加多少0.01M *TEOS?才能制取壳厚度约为10nm的AU@SiO2呢?
文献上都没提这个,有没有做过的指导一下啊?

They found that the addition of TEOS and water prior to ammonia to be critical to obtain a proper coating; and the silica shell thickness was varied from 30 to 90 nm for TEOS concentrations of 0.0005–0.02 M at 10.9 M of water and 0.4 M of ammonia. However, this method was still similar to the method proposed by Liz-Marzan and co-workers, and had not be used for coating the commercial gold nanoparticles
