Objective

To synthesize BSA-AuNPs and run UV-Vis on the invertase-AuNP solutions created yesterday.

Procedure

Preparing Invertase-AuNP Samples for UV-Vis

  1. Centrifuge 1mL of the sample for 30 min at max rpm.
  2. Take UV-Vis measurements of the samples.


Creating the Gold Stock Solution

  1. Add 0.0562 g of HAuCl4·3H2O to a 50 mL volumetric flask and fill with distilled water.
  2. The final concentration of gold stock was 2.85 mM.


Creating the BSA Stock Solution

  1. Add 0.0432 g of BSA to a 50 mL volumetric flask and fill with distilled water.
  2. The final concentration of BSA stock was 21.8 mM.


Solutions with the following Au:protein ratio were synthesized:

Gold to BSA Ratio
  • 105
  • 110
  • 115
  • 120
  • 125
  • 130
  • 135
  • 140
  • 145
  • 150


  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.
