“…Various strategies have been developed, such as the design of graphene foam [35], assembly with the assistance of templates [36], the recombination of graphene and carbon nanotube [37], and introduction of heteroatoms into graphene lattice [38]. Among them, nitrogen doping has been an effective way to improve the sensing properties of graphene for electrochemical sensors [39][40][41]. As is well known, N-doping would further promote the electrochemical performance of graphene electrodes, which could be attributed to more active sites induced by doping, and the increased specific surface area.…”

A novel voltammetric sensor was developed by modifying screen-printed graphite electrode (SPGE) with nitrogen doped graphene sheets (N-GSs) to detect bisphenol A. The electrochemical results exhibited that N-GSs / modified SPGE has high sensing performance towards the oxidation of bisphenol A. Excellent results were obtained for bisphenol A detection in the linear range from 0.08 to 300.0 µM with a sensitivity of 0.1626 µA µM-1 and limit of detection of 0.02 µM. Also, the fabricated N‑GSs/SPGE sensor showed good stability. The as-prepared sensor was tested towards the detection of bisphenol A in real samples. The measured results established the great sensing ability of N-GSs/SPGE for bisphenol A with high selectivity and good stability in real samples.

“…The glassy carbon electrodes (GCEs) become an optimal choice for studying the electrochemical properties of compounds 1-3, because of their good electrical conductivities and high chemical stabilities. [36][37][38] In order to investigate the electrochemical behaviors of compounds 1-3, the three compounds have been used as modiers to fabricate chemically modied electrodes (1-GCE, 2-GCE and 3-GCE). The cyclic voltammetric behaviors for 1-GCE, 2-GCE and 3-GCE in 0.5 mol L À1 Na 2 SO 4 + 0.01 mol L À1 H 2 SO 4 aqueous solution at different scan rates were recorded with the scan rate varying from 80 to 200 mV s À1 for 2-GCE, from 50 to 200 mV s À1 for 1-GCE and 3-GCE.…”

An efficient and simple method has been demonstrated for the synthesis of nickel oxide nanostructures using urea as a capping agent. The nanosheet-like morphology was confirmed by scanning electron microscopy, crystalline nature was studied by using the X-ray diffraction (XRD) and surface area of nanomaterial was investigated by automated sorption analyzer. Then synthesized NiO nanostructures were used to fabricate the surface of glassy carbon electrode (GCE). The electrocatalytic parameters of modified NiO/GCE electrode were investigated by using various techniques such as electrochemical impedance spectroscopy (EIS), square wave voltammetry (SWV), differential pulse voltammetry (DPV), normal pulse voltammetry (NPV) and cyclic voltammetry (CV) and chronoamperometry. Various working experimental conditions were optimized in order to attain the highest sensitivity for the determination of urea and the highest peak current 1032 A of response were obtained at 100 M concentration of urea. A linear calibration plot was obtained for peak current versus concentration of urea in the range of 10 M urea to 80 M urea with a good detection limit of 2 M. The proposed working strategy was successfully employed for the estimation of urea in human urine samples and the obtained results are found satisfactory. The newly functional urea sensor can be exploited at large scale as an alternative analytical device beside to the other reported urea sensors.
