How should I deposit a mono layer of gold nanoparticles (suspension in citrate buffer ) on a screen printed carbon electrode (purchased) using Langmuir?
You can refer the attached paper ..... It could be helpful...
Gold nanoparticles were deposited onto a screen-printed carbon electrode surface according to the methods described with slight modification. In brief, the screen-printed carbon electrode was immersed in a 0.01 M of gold seed solution, which was prepared by mixing 0.5 mL of 0.01 M HAuCl4, 0.5 mL of 0.01 M trisodium citrate dehydrate, and 18 mL of deionised water. After two hours of immersion, the screen-printed carbon electrode was removed from the gold seed solution and rinsed with deionised water and then dried with nitrogen gas before soaking in gold growth solution for 24 hours
Rakesh Sonker thank you for your help,
i buy gold nano-particles suspension in citrate buffer with 20nm size, is this the gold seed solution you mentioned? and now i have to just immerse the sensor in this solution?
also i have no idea what is the gold growth solution? can you clarify it?
any information will be appreciated
thank you
