Calculating [AuNP] in Au@SiO2/DNA-MB solutions

  • Original [Au@SiO2] = 5nM before attaching DNA

1) Addition of 5uL APS

(1mL)(5nM)=(1.005mL)(x)

x = 4.975nM

2) Addition of 1.5mL Sulfo-SMCC

(1.005mL)(4.975nM) = (x)(2.505mL)

x = 1.996nM

3) Centrifugation, removal of supernatant, and redispersion in 530uL KP buffer

(1.996nM)(2.505mL) = x(0.530mL)

x = 9.43nM

4) Addition of 270uL DNA

(9.43nM)(530uL)=x(800uL)

x = 6.25nM
