In this study, the interaction between codeine and morphine with dsDNA was assessed at
pH 7.0. Poly (diallyldimethylammonium chloride), PDDA, was used as a dispersant of
MWCNTs. Using differential pulse voltammetry (DPV) at pencil graphite electrode (PGE)
showed that both molecules were electrochemically oxidized due to the presence of
phenolic and amino groups in their structures. When DNA was added to the solution, the
electrochemical signal of codeine and morphine was decreased and shifted to more ...
