Dissociation of the three polyA₁₀, polyA₂₀, polyA₃₀ DNA from AuNPs surface as a function of DNA sequence, salt, EDTA (2 mM), temperature, and ethanol (80%). All samples contained 100 mM NaCl, pH 7.4. (A, B, C) Dissociation of the polyA₁₀ DNA, polyA₂₀ DNA and polyA₃₀ DNA from AuNPs surface at different storage conditions. (D) Comparison of the DNA desorption kinetics come from the 3 different kinds of DNA AuNPs conjugates. polyA₁₀ DNA−AuNPs (black block), polyA₂₀ DNA−AuNPs (red dot) and polyA₃₀ DNA−AuNPs (blue triangle) contained 100 mM NaCl, in 26 °C.
