A poly(nickel(II) tetrasulfophthalocyanine)/multi-walled carbon nanotubes composite modified electrode (polyNiTSPc/MWNTs) was fabricated by electropolymerization of NiTSPc on MWNTs-modified glassy carbon electrode (GCE). The modified electrode was found to be able to greatly improve the emission of luminol electrochemiluminescence (ECL) in a solution containing hydrogen peroxide. Glucose oxidase (GOD)...
The electrostatic assembly of calf thymus DNA on multi-walled carbon nanotubes (MWNTs)-modified gold electrode via poly(diallyldimethylammonium chloride) (PDDA), a cationic polyelectrolyte, has been studied. Piezoelectric quartz crystal impedance (PQCI) technique was employed to monitor the assembly of DNA in real time. Electrochemical impedance spectroscopy was also used to characterize the modification...
Immobilization of DNA on carbon nanotubes plays an important role in the development of new types of miniature DNA biosensors. Electrochemical characteristics of the immobilization of calf thymus DNA molecules on the surfaces of multi-walled carbon nanotubes (MWNTs) have been investigated by cyclic voltammetry and electrochemical impedance analysis. The peak currents for Fe(CN) 63- ...
