Characterization of DNA immobilized on electrochemically prepared conducting polypyrrole-polyvinyl sulfonate films.

Abstract

The article describes the adsorption characteristics of DNA onto electrochemically generated polypyrrole-polyvinyl sulfonate (PPY-PVS) films obtained as a function of pH. Adsorption on PPY doped with an anion proceeds by anion exchange, and since DNA possesses a fixed negative charge owing to PO4-, it favors a very strong binding displacing PVS with favorable energetic interactions. Characterization of adsorbed DNA onto the PPY-PVS films was carried out by ultraviolet-visible, Fourier transform infrared spectroscopy, and cyclic voltammetric studies.
