Reaction and UV-Vis Kinetic Analysis of Proteinase-K and Gold Nanoparticle Fibers (redo)Today our group performed a reaction between AuNP fibers and proteinase-K, a protease that has previously degraded the fibers with ease. To our surprise, gold was not visible in solution at the end of the reaction today. Three observations about the solution were made:
The final solution's absorption spectra is shown below: XXX The procedure for today's experiment can be found here: User:Andrew_W_Long/Notebook/CHEM-671_Research/2015/09/09. The only modification was that Tris buffer was used in place of water in the reaction mixture. Higher concentrations of protein fibers were used as well (5 1mL tubes previously prepared by the EBC class). |
