Scaled up Silica-Coating Procedure

Original: 1mL AuNP & MHA solution/2μL TES/0.125mL NH4OH/5mL propanol

1) Re-scale to use 9mL AuNP/MHA solution

New: 9mL AuNP&MHA solution/18uL TES/1.125mL NH4OH/45mL propanol

2) Stir solutions for one hour to allow reaction to proceed

3) Centrifuge solutions at 4000 rpm for one hour

4) Re-suspend particles in water

Calculations

Original concentration of AuNP/MHA solution is 4.7nM

4.7nM(9mL)=55.143mL(x)

x= 0.767nM

0.767x10^-9moles/L x 1L/1000mL x 55.143mL = 4.23 x 10^-11 moles AuNP total

4.23 x 10^-11 moles AuNP x 6.02 x 10^23 particles/mole = 2.55 x 10^13 total Au nanoparticles
