ABSTRACT
The Vitrus vinifera fruit extract was used to make silver nanoparticles (AgNPs) utilizing a green chemical technique. The biosynthesized Tween-20/Vitrus vinifera-AgNPs were observed by UV-Vis spectrophotometry. Fourier transform infrared spectroscopy, scanning transmission electron microscopy, selected area electron diffraction, and energy-dispersive X-ray spectroscopy were used to characterize the physiochemical properties. The spherical form of AgNPs was confirmed by transmission electron microscopy. The peaks in the Tween-20/Vitrus vinifera-AgNPs have an average crystallite size that is found to be 46 nm according to powder X-ray diffraction examination. Biosynthesized AgNPs had a significant effect on bone osteosarcoma MG63 cells with 55% inhibition, respectively, using MTT assay. The effective dangerous concentration of Tween-20/Vitrus vinifera with AgNP nanoparticles was less harmful to MG63 cells. The results of antibacterial activity showed that Tween-20/Vitrus vinifera-AgNPs effectively inhibited Eggerthella lenta and Staphylococcus epidermis bacteria.

Bismuth sulfide (Bi2S3) nanowires were synthesized successfully by a facile sonochemical method from Bi(DTC)3 as a single source precursor. The structural, vibrational, morphological properties and the functional groups of the samples were confirmed by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis and Raman spectroscopy techniques. The formation of pure phase of Bi2S3 and nanowires like morphology was confirmed by powder XRD and SEM analysis. The purity and elemental composition of Bi2S3 nanowires were confirmed by EDX analysis. The electrochemical properties of Catechol (CC) at the modified electrode were studied with the presence of Bi2S3 nanowires modified GCE electrode in aqueous solution with different scan rate and concentration. A novel method for determination of catechol using cyclic voltammetry (CV) was investigated. The homogeneous rate constants were estimated by comparing the experimental CV responses with the digital simulated results.
