(a) Anodic peak current for [Fe(CN)6]3−/4− redox probe recorded at Au/MUCS/dsDNA and Au/MUCS/dsDNA/dox electrodes, in different concentration of target DNA, respectively. (b) Linear relationship between the relative current change of the anodic peak [Fe(CN)6]3−/4− redox probe and the logarithm of the target DNA concentration at Au/MUCS/dsDNA and Au/MUCS/dsDNA/Dox electrodes, respectively.
