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.
