*Peaks are seen at 430nm but not 528nm, the point of interest for AuNPs. The peaks at 420nm do not change relative to the change in background. Change in background has in the past been attributed to the use of plastic, rather than quartz cuvettes. | |||
*It's possible that the salt in solution is competing with the HAuCl<sub>4</sub> and preventing it's reduction. Dialyzed ADA should be analyzed. | |||
