Copper Nanoparticle Modified Pencil Graphite Electrode for Electroanalysis of Adenine
Electroanalysis, 2016AbstractA pencil graphite electrode (PeGE) modified with copper nanoparticles (CuNPs) was employed for sensitive electrochemical detection of adenine (Ade). The CuNPs were synthesized by the chemical reduction of copper (II) sulphate by borohydride in the presence of polyvinylpyrrolidone (PVP) and immobilized onto the electrode surface by means of ...

The performance of the new modified pencil graphite electrode in quantifying of insulin
Chemical Physics Letters, 2020Abstract Herein, a new modified pencil graphite electrode (PGE) is presented for insulin assessing and quantifying. For this approach, Ni-nanoparticles (NiNPs) and methylbenzoate (MB) were decorated on PGE using cyclic voltammetry (CV) technique for producing the PGE/NiNPs/MB platform.

A novel disposable pencil graphite electrode for the voltammetric determination of cysteamine
Materials Today: Proceedings, 2019Abstract A highly sensitive electrochemical sensor was fabricated using disposable pencile graphite electrode for the determination of cysteamine. Electrode characterization was done using scanning electron microscopy and X-Ray diffraction studies. The electrochemical properties of the PGE were studied using cyclic voltammetry and differential pulse ...

Facile Preparation of Gold Nanoparticle Modified Pencil Graphite Electrode
Key Engineering Materials, 2017The purpose of this research was to prepare gold nanoparticle (AuNP) modified disposable pencil graphite electrode (PGE). The AuNP was prepared using trisodium citrate reduced gold ion solution. The PGE surface modification was carried out by immersing a bare PGE in poly (diallyldimethylammonium chloride) (PDDA) and then in AuNP solution at room ...

The pencil graphite electrode in the voltammetric analysis of biological important compounds
Conferinţa ştiinţifico-practică internaţională "Instruire prin cercetare pentru o societate prosperă" = International scientific practical conference "Education through research for a prosperous society", 1-2 martie 2025. Vol. 1: Ştiinţe ale Naturii = Natural SciencesVoltammetric techniques represent reliable, inexpensive and rapid alternatives for the analysis of many biologically important compounds. On the other hand, redox reactions are found in many processes essential to life and voltammetric techniques allow the understanding of the mechanisms of some of them.
