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 ...

Differential pulse voltammetric determination of eugenol at a pencil graphite electrode
Materials Science and Engineering: C, 2016In this study, the electrochemical behavior of eugenol, a widely used herbal drug, was investigated at a pencil graphite electrode (PGE). A low-cost, disposable, sensitive and selective electrochemical sensor is proposed for the determination of eugenol by recording its differential pulse voltammograms in Britton-Robinson buffer solution containing 0.1

Application of Disposable Biosensor for Nivolumab–DNA Interaction Using Pencil Graphite Electrode
Russian Journal of Electrochemistry, 2023Abstract: In this study, the interaction of the anticancer drug Nivolumab (NIVO) with dsDNA was investigated using differential pulse (DPV) technique by monitoring the changes in the oxidation signal of adenine and guanine bases on PG electrode. Surface characterization of the PG (pencil graphite) electrode was carried out using cyclic voltammetry ...

Electrocatalytic oxidation of NADH using a pencil graphite electrode modified with quercetin
Colloids and Surfaces B: Biointerfaces, 2013In the present study, the electrocatalytic oxidation of reduced β nicotinamide adenine dinucleotide (NADH) was investigated using a pencil graphite electrode modified with quercetin (PGE/QH(2)). The PGE/QH(2) was prepared through two steps: (i) the pre-treatment of PGE at 1.40 V vs.

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 ...

Electrochemical paracetamol detection using disposable pencil graphite electrodes
European Journal of Life SciencesParacetamol (Par) is a widely consumed antipyretic and analgesic drug. Its global use to reduce or prevent fever is increasing day by day, especially after the pandemic era. It has been detected in natural water resources and has emerged as a potential water contaminant.Therefore, the development of miniaturized detection platforms for the detection of

Electrochemical detection of enzyme labeled DNA based on disposable pencil graphite electrode
Journal of Pharmaceutical and Biomedical Analysis, 2005Electrochemical biosensor for the detection of DNA hybridization using the reduction signal of alpha-naphthol is described. A pencil graphite electrode was used as a working electrode. Capture probes were covalently attached on to the pencil graphite electrode surface (PGE) at the 5' end amino group by using N-(dimethylamino)propyl-N'-ethylcarbodiimide

Novel electrochemical sensing of galactose using GalOxNPs/CHIT modified pencil graphite electrode
Carbohydrate Research, 2019For the construction of galactose biosensor, chitosan was electropolymerised onto the pencil graphite electrode. This chitosan modified pencil graphite electrode acts as good matrix for immobilization of enzyme nanoparticles of galactose oxidase. Development of this nanocomposite was further confirmed by Fourier transform infrared spectroscopy and ...
