Objective

To synthesize hemoglobin-AuNPs and lysozyme-AuNPs.

Procedure

Creating the Gold Stock Solution

  1. Add 0.0524 g of HAuCl4·3H2O to a 50 mL volumetric flask and fill with distilled water.
  2. The final concentration of gold stock was 2.66 mM.

Creating the Lysozyme Stock Solution

  1. Add 0.0717 g of lysozyme to a 50 mL volumetric flask and fill with distilled water.
  2. The final concentration of lysozyme stock was 100.28 μM.

Creating the Hemoglobin Stock Solution

  1. Add 0.0117 g of hemoglobin to a 50 mL volumetric flask and fill with distilled water.
  2. The final concentration of hemoglobin stock was 15 μM.


Solutions with the following Au:protein ratio were synthesized:

Gold to Hemoglobin Ratio
  • 30
  • 50
  • 70
  • 90
  • 110
  • 130
  • 150
  • 170
  • 190
  • 210
Gold to Lysozyme Ratio
  • 5
  • 10
  • 15
  • 20
  • 25
  • 30
  • 35
  • 40
  • 45
  • 50


  1. As seen below, the corresponding amount of protein was added to a 50 mL volumetric flask and filled with distilled water. The samples were made in small test tubes and capped with aluminum foil.
  2. The samples were heated at 80°C for 4 hours.

Data

  • Lysozyme Solutions

  • Hemoglobin Soultions
