Objectives Take down observations for AuNPs solutions made yesterday Measure pH for each AuNP solution Run UV-Vis for each AuNP solution Observations Photos of AuNP solutions can be found here Most amino acids form AuNPs, except for Cysteine and Methionine. This is expected as it agreed to our previous results. Proline, Alanine, Valine, Phenylalanine, Serine, Aspartic Acid, Tryptophan, Leucine formed AuNPs that was suspended in solution Tryptophan formed gold nano fibers The rest of the AuNPs crushed out of solution, forming grey colors, or greyish black precipitates at the bottom of the test tube. Data To be updated
