investigation of the redox properties of drugs and their determination are performed by electrochemical techniques. data obtained from electrochemical techniques are often correlated with molecular structure and pharmacological activity of drugs. in this regard, different modified electrodes were applied as sensors for quantification of different drugs.a nanocomposite of reduced graphene oxide-...
As electrode materials for analytical applications, carbon-based electrodes have been widely employed as detectors for high performance liquid chromatography (HPLC), capillary electrophoresis (CE) and various biosensors. Carbon materials usually shows wider potential window compared with those of novel metals such as platinum and gold electrode. These electrodes are chemically stable, highly co...
Herein, fast Fourier transformation square-wave voltammetry (FFT-SWV) as a novel electrochemical determination technique was used to investigate the electrochemical behavior and determination of Riboflavin at the surface of a nanocomposite modified carbon paste electrode. The carbon paste electrode was modified by nanocomposite containing Samarium oxide (Sm2O3)/reduced gra...

reduced graphene oxide film was synthesized on a glassy carbon electrode by electro reduction of graphene oxide powders in aqueous solution. then platinum nano particles were deposited on reduced graphene oxide film that was deposited on the glassy carbon electrode via electro reduction of platinum salt. the physical morphology of the platinum on reduced graphene oxide film was evaluated by sca...
abstract the graphene–chitosan composite film modified glassy carbon electrode was fabricated and used to determine amlodipine besylate. in 0.1 m ph 7.3 phosphate buffer solutions, the redox peak currents of amlodipine besylate increased significantly at graphene–chitosan composite film modified glassy carbon electrode compared with bare electrode and chitosan modified glassy carbon electrode, ...
