Sample Prep BSA Ocean Optics Solution pH 8 [Au]=0.25 mM [BSA]=3.125 uM Vf=3000 uL Stock Concentrations 160920 [BSA]= 63.1 uM [Au]= 2.39 mM [NaOH]= 1 mM Volumes for making the solution: 148.9 uL BSA 255.6 uL Au 2565.4 uL HOH 3 uL NaOH Results and Data Analysis The above chart displays the absorbance at 535.15 nm of the pH 8 solution with 0.25 mM Au and 3.125 uM BSA over time. The chart shows a gradual increase in absorbance over the run time. The above chart shows the maximum wavelength (nm) of the pH 8 solution with 0.25 mM Au and 3.125 uM BSA over time. The chart displays a plateau of max wavelength ~485 nm until about ~3800 seconds, where it jumps dramatically to about ~550 nm; then leveling off between 530 and 540 nm. The above chart shows the gradual increase in the maximum absorbance of the pH 8 solution with 0.25 mM Au and 3.125 uM BSA over time.
