ObjectiveAuNP III To synthesize gold nanoparticles (AuNP) using the procedure developed here:
http://pubs.acs.org/doi/abs/10.1021/jp110296y
To begin culturing bacteria to express inteins.
To transform DNA coding for mutant GFP (mutated on 09/20/11) into Novablue cells. DescriptionAuNP III
Starter Culture Media, Protein Expression
DataAuNP III The absorbance values for the AuNP solution were subtracted from the absorbance values for a blank acetate buffer to create a set of corrected absorbance values. The corrected absorbance values at 550 nm were graphed against time. The graph shows a positive linear relationship, indicating that AuNPs were formed in solution. In addition, a second graph showing corrected absorbance against wavelength was created, to show the absorbance levels across all of the wavelengths measured by the UV-Vis. A magnified version of this graph shows that absorbance values at around 550 nm increased over time, indicating the creation of AuNPs.
Plate did not appear to be successful; no cells grew. NotesThe AuNP solution turned from clear to purple while in the oven, indicating that AuNPs were actually formed.
