Objective

  • Spin down samples of 30:1 lysozyme-AuNP with 1M salts added and run UV-Vis.
  • Heat samples 30:1 lysozyme-AuNP with 1M salts at 37°C overnight.
  • Image results of 30:1, 55:1, and 110:1 lysozyme-AuNPs synthesized with salt added before heating using UV-Vis.
  • Run atomic absorption of 30:1, 55:1, and 110:1 lysozyme-AuNPs synthesized with salts added before heating.

Procedure

Atomic Absorption

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 were run on the AA:

  • 30:1 MgCl2, CaCl2, NaCl, KCl
  • 55:1 MgCl2, CaCl2, NaCl, KCl
  • 110:1 MgCl2, CaCl2, NaCl, KCl

UV-Vis

UV-Vis For Solutions that Contained Salt Before Lysozyme AuNP Synthesis

UV-Vis For Select Variables at More Refined Concentrations

  • Please Note that the Control Wasn't Diluted With Variable Like the Other Samples.

  • Based off of all UV-Vis data: The ABS for the controls were corrected for the dilution factor present and the percent AuNP's in solution was calculated.

Notes

  • These results detail the samples from last Thursday with the addition of the variables to 1 mL aliquots of 30:1 ratio with salts added after.


  • These results detail the reaction of the different ratios synthesized with salts added before heating.
