FCS Measurements for the Au@Si/DNA-MB samples were run twice each for 7 minutes at a time. Looking at the N values, we have determined that the range for detection is between the 50X and 100X diluted samples (AuNP concentrations of 110pM and 55.2pM respectively.) The Au/DNA-MB samples were not run for this day as they required a few hours to cool to room temperature. This being said, they will also be run in this same 50X-100X diltuion range. | |||

Calculating [AuNP] in Au@SiO2/DNA-MB solutions
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 5) Addition of 13.3uL 7.61uM MB to 100uL Au@SiO2/DNA 6.25nM(100uL)=x(113.3uL) x = 5.52nM
