We made new stock solutions of our red and purple AuNPs to test via UV-Vis for a calibration curve. We need to varify that our calibration curve made on 02/03/2016 is accurate. According to that data, our purple nanoparticles absorbed the fastest, even though they are the largest nanoparticles. Since our red nanoparticles are smaller, it is expected that they would absorb faster. Since these results do not match what we would expect, the nanoparticle standard solutions for both red and purple were both made to reanalyze via UV Vis to verify that our results are correct.
Synthesis of Citrate AuNPs:
Since we want one red and one purple AuNP solution, one of the solutions was stopped early when it was pruple, and the other was left to react until it turned red.
Preparation of "Spring" Water
Although the purple solution was stopped early, the solution kept reacting, creating more red nanoparticles. We are planning on repeating the synthesis tomorrow in hopes of creating purple AuNPs.
