Simultaneous determination of purine and pyrimidine bases in DNA using poly(3,4-ethylenedioxythiophene) /graphene composite film Original Research Article Journal of Electroanalytical Chemistry, Available online 13 October 2014, Pages Xiaoqian Ouyang, Liqiang Luo, Yaping Ding, Bingdi Liu, Duo Xu
Graphical abstractElectrocatalytic oxidation of purine and pyrimidine at different electrodes was investigated by differential pulse voltammetry. The peak currents of G, A, T, C increased significantly and the peak potentials shifted negatively at PEDOT/GR/GCE, demonstrating that the combination of the excellent properties of GR and PEDOT enhanced the kinetics of the electrochemical process as an efficient promoter. DPVs of GCE (a), GR/GCE (b), PEDOT/GCE (c), PEDOT/GR/GCE (d) in the presence of 20.0 μM G, 20μM A, 100 μM T and 100 μM C, and PEDOT/GR/GCE (e) in blank pH 7.4 PBS.

Graphical abstract
A novel leaf-like CuO/graphene nanosheet (GNS) with tunable size was prepared by a facile hydrothermal process, and the stirring temperature in synthesis was found to be effective for controlling the size of it. | |
