Determining Processes of Isolating Gold Nanoparticles Using Refolding Buffers


-Synthesizing AuNP solutions. (purple solution)

-UV-Vis of Solution 1 (Au/BSA mole ratio = 70) synthesized on 31/01/2012


-Determining the effect of tris on solution 2 (Au/BSA mole ratio = 166) synthesized on 31/01/2012



Synthesizing AuNP

  1. Combine 2 mL of 3.66 mM HAuCl4 and 6.04 mL of 0.0173 mM BSA in a test tube.
  2. Dilute to 20 mL with water.
  3. Place in oven at 80°C.
  4. Leave solutions in oven for 3 hr.
  5. Continue to take UV-vis data of 1 mL 70 Au/BSA ratio solution synthesized on 01/31/12 over time.

Determining the effect of tris buffer on 166 Au/BSA ratio solution

  1. Take UV-vis data of 166 Au/BSA ratio solution synthesized on 01/31/12.
  2. Add 2 mL 50 mM tris buffer (pH 10.1) to solid protein fibers (no solution).
  3. Allow fibers to settle.
  4. Take UV-vis data of tris/fiber solution.
