interfacing cytochrome c to electrodes with a dna-凯发网

multi-walled carbon nanotube (mwcnt) is successfully immobilized on the surface of platinum electrode by mixing with dna.the dna/mwcnt modified electrodes are characterized by electrochemical impedance spectroscopy and cyclic voltammetry.further research indicates that cytochrome c can strongly adsorbed on the surface of the modified electrode, and forms an approximatemonolayer. the immobilized mwcnt can promote the redox of horse heart cytochrome c which gives reversible redoxpeaks with a formal potential of 81 mv vs sce.
