Day 2 (9/4)

We redid the synthesis of the three morphologies of AuNPs because the lack of color present in our initial samples. We prepared new solutions of KBr, HAuCl4, CPC, and Ascorbic Acid while still using the same AU gold seed that was synthesized during the summer.

Using these new solutions, we prepared six new samples (two for each morphology) and went through 5 rounds of centrifuging once again and dropped the ethanol volume from 200uL to 150uL.

These samples all had visible colors with the cubic solution being dark orange, the octahedral solution being burnt red and the RD solution being dark purple.
