Noncovalent Interactions of Tiopronin-Protected Gold Nanoparticles with DNA: Two Methods to Quantify Free Energy of Binding
Figure 3
(a) CD titration of AuNPs with DNA in water. [DNA] = āM. Curves from (i) to (xv) correspond to 0, 0.15, 0.29, 0.39, 0.58, 0.71, 1.00, 1.50, 2.00, and 4.00āM of AuNPs. (b) Plot of the molar ellipticity experimental data versus AuNPs concentrations. Symbols () are experimental data and line is the best fit using (2).
