Dilutions of AuNP, MB, and thiol DNA Solution

Goal: dilute solution to 1-0.5nM AuNP
(9.7nM)V=(4.85nM)(100μL)
V= 50μL 9.7nM AuNP in 50μL

Serial Dilutions with 50mM HEPES buffer:

4.85nM
2.425nM
1.2125nM
0.61nM
0.303nM

FCS Data
  • 0.3nM

Τ=0.00018 ms
N= 0.41

  • 0.61nM

Τ=184.456 ms
N= 620

  • 0.3nM (trial 2)

Τ=0.2046 ms
N= 12

  • o.61nM (trial 2)

Τ=0
N=0

Prepare Smaller Intervals of Diluted Samples:

(2.425nM)V=(0.5nM)(50μL)
V=10.3μL in 39.7μL HEPES buffer
0.4 nM → 8.2μL in 41.75μL
0.3 nM → 6.2μL in 43.8μL
0.2 nM → 4.1μL in 45.95μL
