*Based on the relatively static graph, or due to the lack in a shift in the spectra overtime shows that the HRP linked to the AuNP's is inactive. | |||
*This inactivity is most likely explained by the method of synthesis. If the heat was too high while preparing the HRP-linked nanoparticles it could have denatured the protein. | |||
[[Image:Oct_17_Abs_vs._time_@420nm.png]] | |||
*This graph represents the change in absorbance overtime at the wavelength where HRP is most active. Due to the fact that the graph in horizontal for all but the first point dictates that HRP most likely is inactive or its activity is interrupted by being linked to AuNP's. | |||
*The first point shows the solution at time zero before the HRP-AuNP's were added. As a result this big jump was to be expected. | |||

*The spectra represented below are going to be used to compare the different nanoparticles synthesized in lab. Note that the BSA nanoparticles aren't shown here because they had to be remade in lab last class due to the previous batch solidifying. | |||
