The purpose of this subset of experiments was to monitor the change in concentration of AuNPs at various pHs (7.55 and 7).
The increase in concentration at 550 nm observed after 60 minutes appears rather peculiar. An increase in concentration would be expected to continue or at least plateau for the duration for the duration of the experiment. In this case, the concentration returns to baseline readings. I conclude that this increase is instead an error introduced into our 60 minute trial.
