Procedure

Make citrate gold nanoparticles

  1. 1.158mL of 10mM HAuCl4 added to 50mL of water
  2. Heat solution until it boils
  3. 0.5mL of 10mg/mL citrate sodium added to solution and heated until color changes from dark blue to red
  • Making HAuCl4
    • Add 0.0413g HAuCl3 to 10mL volumetric flask
  • Making sodium citrate solution
    • Add 0.250g sodium citrate into 25mL volumetric flask


Determine the size of the nanoparticle solution

Data

  • We heated the above solution and it did not turn blue
    • Possible that not enough gold was added
  • We then made a new solution where we added 2mLs of 10.48mM gold solution
    • The solution turned blue and then red after the sodium citrate was added
