graphic file with name adna-3-80-g4.jpg — Figure 4. SQWV signal at (aegPNA)₁₀-lys₄ modified (A) BDT/AuNP nanostructured surface, (B) BDT/AuNP nanostructured surface blocked with MESNa and (C) BDT/AuNP nanostructured surface blocked with SC₃OH. Voltammetric traces are recorded in 1 mM [Fe(CN)₆]^4- 0.1 M PBS before (blue traces) and after the immersion in solutions containing either 3 nM of the non-complementary (green traces) or 2 nM of the complementary (red traces) oligonucleotide sequence.
