Objective

  • Take conductivity measurements on room temperature solutions from 3/26/14.
  • Run UV-Vis and AA on solutions at 4°C from 3/26/14.

Atomic Absorption Preparation

Creating the Gold Stock Solutions

  1. Add 50 μL of HAuCl4·3H2O and 4950 μL of distilled water to a Falcon tube, for a final concentration of 10 μg/mL Au.
  2. Add 100 μL of HAuCl4·3H2O and 4900 μL of distilled water to a Falcon tube, for a final concentration of 20 μg/mL Au.
  3. Add 150 μL of HAuCl4·3H2O and 4850 μL of distilled water to a Falcon tube, for a final concentration of 30 μg/mL Au.
  4. Add 200 μL of HAuCl4·3H2O and 4800 μL of distilled water to a Falcon tube, for a final concentration of 40 μg/mL Au.
  5. Add 250 μL of HAuCl4·3H2O and 4750 μL of distilled water to a Falcon tube, for a final concentration of 50 μg/mL Au.


Atomic Absorption Samples

Solutions with the following Au:lysozyme ratio at 4°C were run on the AA:

  • 30:1 lysozyme-AuNP with 0.03 M MgCl2, CaCl2, NaCl, KCl, MES, citric acid (0.0002316 M 2,2 bipyridine)
  • 30:1 lysozyme-AuNP with 0.06 M MgCl2, CaCl2, NaCl, KCl, MES, citric acid (0.0004544 M 2,2 bipyridine)
  • 30:1 lysozyme-AuNP with 0.09 M MgCl2, CaCl2, NaCl, KCl, MES, citric acid (0.0006772 M 2,2 bipyridine)
