| - | * | + | * To run UV-Vis analysis on Au/BSA solutions at various ratios. |
| + | * To remake solutions that did not give expected results. | ||
| + | * To make Tris Buffer at 100mM at pH 8.0 and 10.0 | ||

| + | ==Notes== | ||
| + | * The original sets of solutions did not form nano-particles, solutions appeared yellow in color. It was predicted that the HAuCl4 reacted with gold specula during the transfer. | ||
| + | * A new set of solutions with different Au/BSA ratios were made beforehand at the same ratio and concentrations. For details of the concentrations, see [[User:Keyun Wang/Notebook/Experimental Biological Chemistry I/2012/08/29|entry from 2012/08/29]] | ||
| + | * The new set of solutions with different ratios of Au and BSA appeared purpose in color. The 60 Au/BSA solution appeared cloudy and white. The 80 Au/BSA solution appeared as a purpose homogenous solution. The Au/BSA solution with other ratios are transparent with purpose fiber formations. | ||
