Objectives

  1. Finish the tasks that weren't completed on February 23rd:
    1. Set up 20 mL samples for silver-casein/rice protein/pea protein, and gold-whey/soy
    2. Run UV/Vis on the 20 mL samples before placing them in the oven
  2. Run UV/Vis on samples ran on Feb. 23rd

Materials

  1. Protein stock solutions made on Feb. 23rd
  2. Gold, silver and citrate stock solutions made on Feb. 23rd
  3. Seven 20 mL tubes
  4. Oven
  5. UV/Vis machine

Procedure

  1. Prepare 20ml reaction to synthesize large quantities of reactions known to work (see link below for specifics on reaction mix). Note: spectra of reaction mixes before reacting were taken
  2. Reaction mix and measurement data can be found at the link SRB Lab Notebook Data and the reaction itself was run on 02/24/16, the reaction mix planning and UV Vis from 02/17/16 was performed on the 02/23/16

Results

  1. Color change notes and UV-VIs information can be found at the link SRB Lab Notebook Data
  2. Whey and Soy gold were in neutral reaction, Pea, Casein and Rice silver were basic - all experience color change (silver=yellow, red/purple = gold)
