求助合成4-5nm的金納米顆粒的方法 已有3人參與
|
||
| 請大家?guī)兔Γ椰F(xiàn)在急需要4-5nm的金納米顆粒，由于需要后續(xù)修飾巰基，因此不能用巰基穩(wěn)定劑穩(wěn)定，最好是用檸檬酸三鈉穩(wěn)定，我之前用過檸檬酸三鈉和單寧酸來制備，但是粒徑比較大，而且我擔(dān)心單寧酸分子量比較大會不會影響后續(xù)修飾？因此想求助用檸檬酸三鈉和硼氫化鈉制備金納米顆粒的方法，請各路大神不吝賜教，感激之至！ |

6納米左右 Monodisperse I-IL-Au NPs were prepared by the reduction of HAuCl4 with sodium borohydride (NaBH4) according to the previous work [20–22] . In brief, firstly the fresh sodium borohy-dride solution (NaBH4, 1 mL, 4.5 mg mL−1) was added dropwise to 100 mL aqueous solution of HAuCl4(1 mL, 8.9 mg mL−1) under vigorous stirring at room temperature. About 15 min, a vivid red colored solution was produced. Finally, after added the amino-functionalized ionic liquid, the gold colloidal solution was stirred for another 2 h to ensure self-assembly of the ionic liquid onto the surface of gold nanoparticles. The synthesized I-IL-AuNPs were purified by centrifugation and redispersed in double-distilled,deionized water twice. The final concentration of I-IL-Au NPs were 57.29 nM calculated using Beer’s law with the extinction coefficients (ε) of 1.1 × 107M−1cm−1 for Au NPs of 5.6 ± 0.4 nm diameter。 |
