conclusions silver nanoparticles were observed to have additive effects with essential oil against staphylococcus epidermidis and s. aureus. the obtained results suggest the need for further investigations of the antibacterial effects of the combination of silver nanoparticles with other plant extracts and essential oils. results the results of the experiment showed that the mic and minimal bac...

Biosynthesis of silver nanoparticles with small size and biostability is very important and used in various biomedical applications. In the present work, we describe the synthesis of silver nanoparticles (Ag-NPs) using seed aqueous extract of Olea europaea (Oe) and its antibacterial activity. UV–visible spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), scan...

A green synthetic approach by using oak fruit hull (Jaft) extract for preparation of silver nanoparticles (AgNPs) was developed and optimized. Parameters affecting the synthesis of AgNPs, such as temperature, extract pH, and concentration of extract (ratio of plant sample to extraction solvent), were investigated and optimized. Optimum conditions for the synthesis of silver nanoparticles are as...

The use of less hazardous chemicals or natural material in place of toxic chemical for the formation of metal nanoparticle is known as green synthesis. The present paper deals with greener approach for the synthesis of silver (Ag) nanoparticles. The Saraca asoca plant leaves extract solution was used for the silver nanoparticles. Confirmation of Ag nanoparticles has been done using var...

The antimicrobial effects of silver (Ag) ion or salts are well known, but the effects of Ag nanoparticles on microorganisms and antimicrobial mechanism have not been revealed clearly. Stable Ag nanoparticles were prepared and their shape and size distribution characterized by particle characterizer and transmission electron microscopic study. The antimicrobial activity of Ag nanoparticles was i...

In this work, at first, nano ZrO2 and Fe3O4/ZrO2 nanocomposite were prepared by sol-gel and co-precipitation methods, respectively. Then, Ag nanoparticles (Ag NPs) were mixed with themin environmentally friendly and mild conditions using C. cyanus flower extract as a reducing and stabilizing agent. The synthesized nanocomposites were characte...

The present work deals with Sphaeranthus indicus leaf extract used as a capping and reducing agent for silver nanoparticles (Ag NPs) synthesis. Synthesized nanoparticles were characterized by UV-Vis, FT-IR, XRD, SEM with EDX and TEM analysis. The UV–Visible spectra of Ag NPs exhibited a surface plasmon resonance peak at 424 nm. FT-IR analysis determined the vibration functional group to respons...

In this research, silver nanoparticles (Ag NPs) were prepared by a low-cost, rapid, simple and ecofriendly approach using Grape fruit extract as a novel natural reducing and stabilizing agent. The product was characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-...
