This work demonstrates that liquid phase deposition (LPD) technique provides a novel approach to the immobilization of hemoglobin (Hb) in TiO 2 film for studying the direct electron transfer of Hb. Using the LPD process, a hybrid film composed of Hb, TiO 2 and sodium dodecylsulfonate (SDS) is successfully prepared on the electrode surface. The surface morphology of as-deposited Hb/SDS/TiO...
A DNA biosensor was constructed by immobilizing DNA on a glassy carbon (GC) electrode modified with multiwall carbon nanotubes (MWNTs) dispersed in Nafion (DNA/MWNTs/GCE). The DNA-modified electrode exhibited two well-defined oxidation peaks corresponding to the guanine and adenine residues of DNA, respectively. The effects of the adsorption potential, DNA concentration and quantity of MWNTs used...
