Hello everyone,
I'm currently working on gold nanoparticles assemblies using L-arginine as the assembling unit. I was wondering if L-arginine is stable on aqueous solution, does it age well?

Hello Manuel Flores
I attached the product information of L-arginine from Sigma Aldrich Merck. In water, L-arginine is soluble up to 50 mg/ml, yielding a clear, colorless solution.
L-arginine is actually often used to stabilize and solubilise other compounds:

Hello Marie Berthuel
Thanks for your quick answer.
I think my question is not accurate enough so i'll try to rephrase it:
What I'm looking to know is if L-arginine is stable on aqueous solution for long periods of time. I'm using it as an assembly unit for the preparation of gold nanostructures but I got mixed results. So I was wondering if L-arginine is not as "good" after X days/months because I didn't get the same results when using an old L-arginine solution (months old) and a fresh L-arginine. I hope this makes things clearer.
In the meantime i'll check the links you posted! Thanks again

Manuel Flores ,
You can still find this answer in the attached paper (product information).
Solutions of L-arginine may be autoclaved. So it is pretty stable to high temperatures and pressures.
When in solution, I would advise to store L-arginine in a buffer (maintain the pH to a certain value) for less than a month in a sealed container. Indeed, as specified in the attached paper, aqueous solutions of this product are strongly alkaline and tend to absorb carbon dioxide from the atmosphere on standing.
