A self-assembly composite of graphene-pyrroloquinoline quinone (PQQ) was fabricated and modified on glassy carbon electrode (GCE) for sensitive detection of nicotinamide adenine dinucleotide (NADH). Chitosan (CTS) was applied to disperse graphene to form a stable robust film on GCE. A synergistic effect between PQQ and graphene was observed during the electrocatalytic oxidation of NADH, with about...
In this paper, a study on a simplified technique of fabricating the new nanocomposites of β-cyclodextrin and multi-wall carbon nanotubes modified ITO electrode (β-CyDex/MWNT/ITO), which was applied to the electrocatalysis for the oxidation of NADH and the satisfactory outcome was obtained. The modified electrodes of MWNT/ITO and β-CyDex/MWNT/ITO were initially prepared and then the cyclic voltammetry...
An anticancer drug dacarbazine (DTIC) was immobilized on a glassy carbon electrode (GCE) by using electrochemical oxidation method. Then the DTIC-modifled GCE was utilized as a stable functional monolayer to further associate with DNA bases and the different blocking effects on the redox reaction of Fe(CN)63- were observed on the different DNA base associated DTIC/GCE, where much bigger blocking...
