Electro analysis of 2-Aminothiazole (2-AT) by a low cost poly Glycine modified Pencil Graphite Electrode (poly Gly/PGE) was studied using of cyclic voltammetric (CV) and differential pulse voltammetric (DPV) techniques. The optimal experimental conditions to determine 2-AT was setup by the variation of the current with scan rate, concentration and pH. Electrochemical performance of the 2-AT at ...

A novel electrochemical sensor for sensitive detection of doxepin was prepared, which was based on a glassy carbon electrode modified with poly(4-aminobenzoic acid)/multi-walled carbon nanotubes composite film [poly(4-ABA)/MWNTs/GCE]. The sensor was characterized by scanning electron microscopy and electrochemical methods. It was observed that poly(4-ABA)/MWNTs/GCE showed excellent preconcentra...

We have developed a simple and selective method for the electrochemical detection of hydrazine (HZ) using poly(dopamine) (pDA)-modified indium tin oxide (ITO) electrodes. Modification with pDA was easily achieved by submerging the ITO electrode in a DA solution for 30 min. The electrocatalytic oxidation of HZ on the pDA-modified ITO electrode was measured by cyclic voltammetry. In buffer soluti...

In the present study, an electrochemical DNA sensing strategy for highly sensitivity detection of DNA hybridization was reported based on a gold nanoparticles (AuNPs) / cysteamine (Cys) / poly glutamic acid (PGA) modified electrode. A glassy electrode was first modified with the polymer film by cyclic voltammetry (CV), and then AuNPs were immobilized on the surface of PGA with Cys as a linker, ...

Quartz crystal microbalance (QCM) electrodes modified with nano-thin films were used to develop a system for measuring significant environment changes (smoke, humidity, hazardous material release). A layer-by-layer approach was used for the deposition of sensitive coatings with a nanometer thickness on the electrode surface. The QCM electrode was modified with self-assembled alternate layers of...

A polymer/mediator composite modified glassy carbon electrode (GCE) is fabricated for electrochemical detection of iodate (IO3 ). Flavin adenine dinucleotide (FAD) is chosen as mediator for sensing iodate, and 3,4 ethylenedioxythiophene (EDOT) is chosen for entrapping FAD and forming a conducting polymeric matrix, poly(3,4 ethylenedioxythiophene) (PEDOT). The PEDOT/FAD modification layer is ele...
