The current work reports the effect of palladium nanoparticles and their nanogeometry on redox electrochemistry tetracyanoquinodimethane (TCNQ) modified electrodes. Palladium were prepared with different concentrations 3-aminopropyltrimethoxysilane calcination at 600 °C to yield PdNP-1 PdNP-2 average size 1 µm 12 nm, respectively. characterized by TEM, XRD, AFM techniques. electrochemical excel...

In the current study, electrochemical removal of reactive orange 7 (RO7) dye in aqueous solution was examined over a novel Ti/nanoZnO–CuO electrode prepared through electrophoretic deposition technique. Surface morphology, crystal structure, and elemental investigation were done by Field emission scanning electron microscopy, X-ray energy dispersive spectrometry, diffraction analysis, which con...

Electrochemical microsensors and biosensors have been widely used in many fields, particular neurochemical monitoring, because of their features. Usually, hydrogen peroxide (HP), obtained as a by-product an enzymatic reaction, is the detected compound on transducers made precious metals, platinum. The over-time increase price platinum its alloys requires use miniaturizable low-cost supports tha...

The objective of this study was to improve the overall performance a glassy carbon electrode (GCE) for detection 2,6-diaminotoluene (TDA), possibly carcinogenic primary aromatic amines (PAAs) that poses serious risk consumer’ health because they can transfer from multilayer food packages including adhesives based on polyurethane (PU) systems, food. modification surface made by means multi-walle...

Polymeric permselective films are frequently used for amperometric biosensors to prevent electroactive interference present in the target matrix. Phenylenediamines most commonly deposition of shielding polymeric against interfering species; however, even phenolic monomers have been utilized creation these microsensors and biosensors. The purpose this paper is evaluate performances electrosynthe...

Abstract A simple and cost - effective electrochemical synthesis of carbon based nanomaterials for biosensor is great challenge these days. Our study describes a single step deposition strategy to prepare nanocomposite electrochemically reduced graphene oxide (ErGO), multi walled nanotubes (MWCNTs), polypyrrole (PPy) in an aqueous solution pH 7.0 dopamine (DA) detection. The ErGO/MWCNTs/PPy nan...

Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...
