"That leaves the tips open to an oxidation or reduction reaction. The ascorbic acid provides electrons that combine with gold ions and settle at the tips in the form of gold atoms. And unlike carbon nanotubes in a solution that easily aggregate, the nanowires keep their distance from one another."

Where they try and grow gold nanoparticles.
What I'm confused with is how they were able to increase the atoms of gold by simply just adding ascorbic acid. I mean the Vitamin C gives the ions electrons, that in turn just converts the ions to atoms? Why did the article seem to make it so that the Vitamin C itself actually turns into gold ions/atoms.
Which brings me to my next Q.
If I have a 1L aqueous solution of gold ions. How much vitamin C needs to be used to gain gold atoms? And how could these atoms be increased in mass without the need to get more Gold? Is this possible since these ions just need electrons?
