Abstract


Conducting PAni/Fe3O4 nanocomposites is use as thin film layer on FTO glass for signal transduction and immobilization of antibody owing to its electrical property. The electrode surfaces were characterized with FESEM,XRD and UV-Vis. The experiment outcome indicated that a conducting layer was form on the FTO coated glass at range of -1.5 to 0.5 V at  0.10Vs-1 in a solution of PAni-Fe3O4. Electrochemical impedance changes occur only after PAni/Fe3O4 bound to surface of bare FTO, confirming deposition and the transducing ability of the new modified electrode for the immobilization of biomarker.
