a carbon ionic liquid electrode (cile) modified with tio2-fe nanoparticles was constructed by incorporating tio2-fe nanoparticles into the paste matrix. under the optimized experimental conditions, using differential pulse voltammetry (dpv), the oxidation of thiocyanate and oxalate were occurred at potentials of 0.740 v and 1.010 v, respectively, at the surface of the modified electrode. observi...

This paper describes for the first time surface modification of glassy carbon (GC) electrodes with bamboo-based renewable (RC) and antimony nanoparticles (SbNPs) determination methylparaben (MePa) in personal care products (PCPs). The synthesized RC-SbNP material was successfully characterized by scanning electron microcopy, energy-dispersive X-ray spectroscopy cyclic voltammetry. proposed sens...

developing simple, sensitive and selective sensing systems for dopamine is important due to its biological significance. in this work, a silver nanoparticles-modified carbon paste electrode (agnps-cpe) has been constructed and used to detect of dopamine (da) in the simultaneous presence of ascorbic acid (aa) and uric acid (ua) at neutral ph 7.0 by cyclic voltammetry. the modified electrode show...

A bifunctional derivative of the thrombin-binding aptamer with a redox-active Fc moiety and a thiol group at the termini of the aptamer strand was synthesized. The ferrocene-labeled aptamer thiol was self-assembled through S-Au bonding on a polycrystalline gold electrode surface and the surface was blocked with 2-mercaptoethanol to form a mixed monolayer. By use of a fluorescent molecular beaco...

In the present work, tungsten disulfide was synthesised and characterised by using X-ray diffraction scanning electron microscopy. This material employed to modify a glassy-carbon electrode analyse clenbuterol. The results show that displays electrocatalytic activity toward clenbuterol oxidation. proposed technique is prospective for examination. limit of detection linear range are 0.51 mM 1–21...

The voltammetric behavior of olopatadine was investigated at hanging mercury drop electrode using cyclic voltammetry and differential pulse voltammetry. The drug under study exhibited a single, well-defined reduction peak owing to the reduction of carbon-carbon double bond. The electrode and reaction conditions which yielded maximum peak current were established using differential pulse voltamm...

In this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (TiO2). The TiO2nanoparticles was characterized by Scanning Electron Microscopy (SEM), x-ray diffraction (XRD) and BET technique.The TiO2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6H-benzofuro [3,2-c] chromen-6-on) were incorporated in a graphite composite ele...
