* In the graph above, the concentration of gold in Au/Lysozyme supernatant increased from mole ratio of 20 to 60, and dropped immediately from mole ratio of 60 and on. From mole ratio of 60 and on, there are no gold present in supernatant. The samples with mole ratio from 60 and on appear transparent as oppose to purple. | * In the graph above, the concentration of gold in Au/Lysozyme supernatant increased from mole ratio of 20 to 60, and dropped immediately from mole ratio of 60 and on.

* This result indicates that protein started to form aggregation from mole ratio of 60 and on. Compare to the result with Au/HRP from above and Au/BSA from [[User:Keyun Wang/Notebook/Experimental Biological Chemistry I/2012/10/17|2012/10/17]], the behavior of Au/Lysozyme resemble more like Au/BSA samples in terms of protein aggregation formation. This result also indicates that BSA and lysozyme behavior similarly when forming gold nano particles. It can also indicate that they have similar protein folding and unfolding kinetic mechanism. | * This result indicates that protein started to form aggregation from mole ratio of 60 and on.

* The table above listed the calculated initial gold concentration in unit of ppm and final measured concentration of gold in ppm in Au/ADA dialyzed samples. The change in gold concentration indicates how much gold nanoparticles were formed. If the percent change of gold is creater than 1, then it means that most of gold were incorporated into gold nanoparticles. When percent change goes below 1, data indicates that there were still some percentage of gold left in solution that were not nucleated within proteins to for gold nanoparticles. | |||
* The graph plotting the percent change in concentration of gold in solution versus the mole ratios of Au/ADA were shown in graph below: | |||
[[Image:AuADA_AAS_Percent.jpg]] | |||
* It can be seen that th percent change in gold concentration were relatively the same. The lowest percent change in gold concentration appeared to be 80Au/ADA. However, this might be due to accidental suspension of nanoparticle fibers when Atomic absorption spectra were taken. | |||
* Aside from the 80Au/ADA data point, the second lowest change in percent change in gold concentration happened to be 60 Au/ADA. This result might indicate that the concentration of gold in solution in 60 folds encouraged less nanoparticle formation compared to Au/ADA samples with greater mole ratios. | |||
* Lastly, the percent chage in gold concentration were roughly the same in remaining Au/ADA samples as the mole ratios goes above 90. This indicates that as the mole ratio increase, more gold were incorporated within gold nanoparticles. This indicates that high mole ratio in solution help facilitate gold nanoparticle nucleation. | |||
