In this study, Nafion-stabilized 2D MXene sheets were synthesized on carbon cloth to address issues of oxidation and leaching, which limit applications in sensing. The prepared electrodes characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, demonstrating enhanced electrochemical properties due the increased active surface area, conductivity, porosity MXenes. Cyclic voltammetry showed a significant increase current from 10 µA 76 with rising...
This work reports the fabrication of an electrochemical glucose biosensor based on functionalized graphene, assembled onto a gold-sputtered screen-printed electrode. With aim simplicity, versatility, and low cost, biosensors dually with graphene oxide containing excess carboxylic acids thiol functionality were synthesized characterized by Fourier transform infrared, Raman, UV–vis spectroscopy. The increased groups backbone provided more active sites for remote functional oxidase during...
Simple detection of acetone is indispensable due to its health and environmental concerns. Surface-modified electrodes are promising for the acetone. In present study, facile fabrication ZnO nanoflakes on carbon cloth (CC) reported. The electrode was fabricated by decorating CC with nanoparticles (ZnO NPs), followed hydrothermal treatment modification diazonium salt using linear sweep voltammetry (LSV) forming NFs) NPs/CC. as-prepared ZnO/CC used at room temperature cyclic voltammetry....
Fruits and vegetables are subjected to post-harvest losses due high moisture contents along with other physiological factors. Among various measure control loses, development of edible coatings has been an imperative innovative technique achieve the desired goal. Opuntia cactus, a xerotrophyte, plant contains appreciable amount polysaccharides thus can be utilized in coating formation. The mandate present study was extract from cactus for their potential applications on citrus fruits. For...
Exploring a robust, extremely sensitive, cost-effective and reliable assay platform for the precise analysis of dopamine (DA) has become big challenge predominantly at clinical level.
A Surface Enhanced Raman Scattering (SERS) substrate based on Ag/β-AgVO3 nanobelts deposited copper foil (Cu@Ag/β-AgVO3) was used for the detection of carbamate pesticides: carbofuran, carbaryl, isoprocarb and propoxur. Cu@Ag/β-AgVO3 has shown an excellent SERS activity pesticides compared to silver nanoparticles (AgNPs). Under optimized conditions, limits 2.5 pM, 10 50 pM 75 were obtained propoxur respectively, suggesting that is a good candidate use as trace level these pesticides.
Herein, we synthesized nickel (Ni)-doped iron oxide nanoparticles (Fe2O3). The presence of the dopant afforded anchoring sites for porphyrinic hetero cavity 5,10,15,20-(tetra-4-carboxyphenyl)porphyrin to produce porphyrin/Fe2O3@Ni composite. crystalline structure and morphology were assessed using various tools including Fourier transform spectroscopy (FTIR), scanning electron microscopy (SEM), atomic force (AFM), X-ray diffraction (XRD) Raman spectroscopy. Porphyrin/Fe2O3@Ni has proven be...
UV induced DNA damage can lead to the development of skin cancer, aging and cell death. In this study, we fabricated a fluorescence-based biosensor that be applied detection caused by radiation with help nitrogen doped graphene quantum dots (N-GQDs) as probe material. paper, N-GQDs good fluorescence efficiency have been synthesized hydrothermal method were used fluorescent for damaged DNA. The intensity was quenched static quenching through formation N-GQD/UV complex. Moreover, effects...
Controlled hydrolytic degradation of ultraphosphate glasses at their branching sites has indicated that these compounds, with a ratio univalent-cation to phosphorus between 0·7–1·0, consist random arrangements trimetaphosphate rings, polyphosphate chains, and branched chains. No ring structures larger than have been found exist in any the ultraphosphates studied.The most likely overall average determined for series compositions from consideration unipositive cation ratio, chain-lengths...
We report the spontaneous fragmentation of gold nanoparticles (AuNPs) induced, in aqueous solution at room temperature, by thiol derivative ubiquinone, which involves energetic electron injection from thiol-ubiquinone to nanoparticles.
