ObjectiveTo determine the effects of ionic strength on AuNP solution and to continue to take UV-vis data over time of 70 Au/BSA solution synthesized on 01/31/11. Description
Data
Additions of concentrations of tris 50 mM or above causes an increase in absorbance and a small blue shift in peak wavelength.
Absorbance values continue to increase over time. However, peak wavelength has leveled off. Notes
