In the present work basic aspects of the bimolecular electron transfer processes have been studied by photochemical means and the heterogeneous electrochemical electron transfer processes have been applied in corrosion research and electroanalysis. Photoinduced electron transfer (ET) reactions were studied from the fluorescence quenching experiments using coumarins and quinones as the fluoropho...

TiO2/WOx nanotubes have unique photo-energy retention properties that have gathered scientific interest. Herein, we report the synthesis, morphological characterization, and the electrochemical characterization of TiO2/WOx nanotubes compared with pure TiO2 nanotubes, prepared by anodization technique. Significant structural differences were not observed in TiO2/WOx nanotubes as observed by usin...

Site-specific electrochemical deposition is used to prepare polystyrene (PS)-Ag Janus particle arrays with superhydrophobic properties. The analyte molecules can be significantly enriched using the superhydrophobic property of the PS-Ag Janus particle array before SERS detections, enabling an extremely sensitive detection of molecules in a highly diluted solution (e.g., femtomolar level). This ...

Due to the rapidity and the effectiveness of the method, the reduction of diazonium salts has been widely used to functionalize electrodes for sensor applications. However, the resulting organic film usually designed to provide complexing capabilities for the species to be determined could affect the sensor properties. The electrochemical reduction of 4methoxybenzene diazonium salt on graphite ...

In this work, a novel label-free electrochemical immunosensor was developed for the quantitative detection of alpha fetoprotein (AFP). Multifunctionalized graphene nanocomposites (TB-Au-Fe3O4-rGO) were applied to modify the electrode to achieve the amplification of electrochemical signal. TB-Au-Fe3O4-rGO includes the advantages of graphene, ferroferric oxide nanoparticles (Fe3O4 NPs), gold nano...

Electrochemical investigations of 1,2,4-triazole and benzotriazole in aqueous acidic media has been carried out by cyclic voltammetric measurements. Cyclic voltammetric experiments were carried on glassy carbon (GC) working electrode. Effect of potential scan rate, pH of the solution and use of different surfactant on the electrochemical behavior has been investigated. Single reduction wave was...
