Main Question or Discussion Point
What are the benefits of oxidizing gold? I suppose that prevents it from rusting, but are there any other benefits?
Almost surely they meant that the gold was exposed to UV-generated ozone and oxygen radicals, and that it was the organic contaminants that were oxidized (and volatalized) to leave the gold as clean as possible before deposition. This is a common procedure.Thank you for your assistance.
This is a bit of a problem then, and my complete lack of Chemistry knowledge compounds this.
My ultimate goal is the deposition of DPPC (a membrane protein) on to gold by vesicle fusion. The paper that I've been referencing claims they used a gold substrate that was oxidized by UV lamp... As I said, apparently our UV cleaner isn't powerful enough to do this, and as was pointed out, oxidation by acqueous solution is not an option....
Perhaps you can expand on this low pressure air plasma? I'm not familiar with it.
