Procedure:Silica-coating AuNPs by MHA, Day Two Round 2

  • Day Two:
    • Prepare the following solutions:
  1. 1mL 9.4nM, 9.65nm AuNP&MHA, isopropanol/4μL TES/0.125mL NH4OH/5mL propanol
  2. 1mL 9.4nM, 9.65nm AuNP&MHA, isopropanol/3μL TES/0.125mL NH4OH/5mL propanol
  3. 1mL 9.4nM, 9.65nm AuNP&MHA, isopropanol/2μL TES/0.125mL NH4OH/5mL propanol
  4. 1mL 9.4nM, 9.65nm AuNP&MHA, isopropanol/1μL TES/0.125mL NH4OH/5mL propanol
  5. 1mL 9.4nM, 9.65nm AuNP&MHA, PBS/4μL TES/0.125mL NH4OH/5mL propanol
  6. 1mL 9.4nM, 9.65nm AuNP&MHA, PBS/3μL TES/0.125mL NH4OH/5mL propanol
  7. 1mL 9.4nM, 9.65nm AuNP&MHA, PBS/2μL TES/0.125mL NH4OH/5mL propanol
  8. 1mL 9.4nM, 9.65nm AuNP&MHA, PBS/1μL TES/0.125mL NH4OH/5mL propanol
    • Stir solutions for one hour to allow reaction to proceed
    • Centrifuge solutions at 4000 rpm for one hour
    • Re-suspend particles in 140uL PBS (per solution)
      • Dilute each solution 10 and 100 times
