Objective Determine the effects of constant temperature and changing temperature on the formation of fibers in solution. Description Gold NPs synthesis: Two test tubes (Test Tube A and Test Tube B) were prepared. Test Tube A contained 0.1ml of BSA, 0.1ml HAuCl4, and 0.8ml of H2O. Test Tube A was placed in the heatblock set at 78°C. Test Tube B contained 0.1ml of BSA, 0.1ml HAuCl4, and 0.8ml of H2O. Test Tube B was placed in the heatblock set at 78°C, was removed in 30 minutes, and was left at room temperature for 10 minutes. Test Tube B was then placed back into the heatblock and the steps were repeated. Data Test Tube A was a clear purple solution. Test Tube B contained purple fibers in clear colorless solution. Notes Both tubes had a molar ratio of HAuCl4 to BSA of 187. Use categories like tags. Change the "Course" category to the one corresponding to your course. The "Miscellaneous" tag can be used for particular experiments, as instructed by your professor. Please be sure to change or delete this tag as required so that the categories remain well organized. .
