Objective Today's experiment consists on creating Gold NPs filaments for further study. So we're doing the same protocol as on the previous Gold NPs synthesis. Protocol 1ml of BSA (15.4µM) 1ml of HAuCl4 (4.3mM) 8ml of water Heat at 80°C, remove the solution from the oven every 30 minutes and leave it at room temperature for 10 minutes Results After having left the solution at room temperature during several days, we don't observe purple fibers but some grey fibers. It seems that the Gold didn't react and mix with proteins to forms Gold NPs. The grey fibers should be formed by BSA proteins.
