Nanoparticles? Citrate ion?


Hi There,

What is the purpose of the citrate ions used when making gold nanoparticles? Is it to prevent continued growth of the nanoparticles? I'm trying to think of at least 2 reasons citrate is used?

Thanks

Citrate is an complex agent for gold ions. Immersion gold bathes also contain this beside cyanide.
