A novel architecture was designed by combining the strong adsorption ability of Fe(2)O(3) microspheres to the DNA probes and excellent conductivity of self-doped polyaniline (SPAN) nanofibers (copolymer of aniline and m-aminobenzenesulfonic acid) on carbon ionic liquid electrode (CILE) for electrochemical impedance sensing of the immobilization and hybridization of DNA. The formed conductive Fe(2)O(3)/SPAN membrane on the CILE was characterized by cyclic voltammetry (CV) and electrochemical… CONTINUE READING
