  1. Atomic Absorption of Lysozyme and Hemoglobin nanoparticles synthesized 11/06/2013
  2. UV-vis measurements of Lysozyme and Hemoglobin nanoparticles synthesized 11/06/2013


Atomic Absorption:

  • Centrifuge 4mL from each sample for 30min at 4000rpm
  • Make standard solutions in the same manner as the last time we performed AA; this time go up to 50ug/mL
  • Take measurements of your standards and samples
  • Make a graph showing concentration of Au vs Au:protein ratio
Gold Standards- Calculations
  1. 50 ug/mL:
    • (1000ug/mL)V=(50ug/mL)(5mL)
    • V= 0.25mL Au stock in 4.75mL water
  • Each sample diluted from Au stock in the above manner

  • UV-vis measurements to be taken tomorrow
