“…The electron-beam reduction for electrode preparation is a novel method that utilizes the idea of reducing ions of the catalyst species right on the carbon cloth fibers and the multi walled carbon nano tubes (MWNTs) via direct electron-beam bombardment [35]. The basic procedure of the method involved an ionic solution, such as PtCl4, then wetted onto the TEM specimen copper grid and dried in the air.…”

“…At MWCNT-GCE, these oxidation peaks appeared at 0.696 V and 0.912 V, respectively, with a considerable enhancement in the peak current. Thus, the negative shifts in peak potentials were observed to be 25 mV and 46 mV for peak a1 and a2, respectively, suggesting that MWCNT exhibited catalytic effect towards electrooxidation of IPH [8,18].…”

The electrochemical behavior of isothipendyl hydrochloride (IPH) was investigated at bare and multiwalled-carbon-nanotube modified glassy carbon electrode (MWCNT-GCE). IPH (55 μM) showed two oxidation peaks in Britton-Robinson (BR) buffer of pH 7.0. The oxidation process of IPH was observed to be irreversible over the pH range of 2.5-9.0. The influence of pH, scan rate, and concentration of the drug on anodic peak was studied. A differential pulse voltammetric method with good precision and accuracy was developed for the determination of IPH in pure and biological fluids. The peak current was found to be linearly dependent on the concentration of IPH in the range of 1.25-55 μM. The values of limit of detection and limit of quantification were noticed to be 0.284 and 0.949 μM, respectively.

INTRODUCTIONNano technology represents one of the emerging areas of modern science and technology. Nanoparticles are the materials which are in the 1-100 nm size domains and act as a bridge between atomic and bulk material. Metal nanoparticles have attracted great interest in modern chemistry and material research due to the large surface to volume ratio and quantum size effects [1][2][3]. They find applications in various fields such as photochemistry, nano electronics, optics and catalysis [4][5][6][7]. Metal nanoparticles were effective against pathogens. The unique properties of metal nanoparticles found to be influenced by the particle size, the organization of the nanoparticle crystal lattice and the chemical nature of the environment surrounding the nanoparticles [8,9]. Metal nanoparticles can be prepared by physical and chemical methods. The physical methods include subdivision of bulk metals, by crushing or pulverization of bulk metal, arc discharge between metal electrodes and so on. The chemical methods include the reduction of metal ions to form atoms followed by aggregation of atoms [10][11][12]. The chemical reductants involve NaBH4, alcohol, LiAlH4 molecular hydrogen hydrazine etc. Green method is an eco-friendly method for the production of nanoparticles, where plant systems are used for the synthesis of nanoparticles [13][14][15][16]. In order to prevent the agglomeration of nanoparticles and produce metal nanoparticles with a narrow size distribution, capping agents are important. Copper nanoparticles perform a key role in catalysis, antimicrobial fields and electronics. Copper nanoparticles were synthesized by various methods and their efficiencies were compared. Green Chemical approach which used citrus lemon fruit extract both as the reduction and capping agent is found to be most efficient and economical method for the synthesis of copper nanoparticles.
