Structural Characterization of Silver Nanoparticles Synthesized by Microemulsion Route

344 Abstract− Silver nanoparticles were synthesized by micro emulsion route in W/S ratio of 5 at room temperature. X-ray diffraction (XRD) pattern reveals FCC structure of Ag nanoparticles. Spherical shape of Ag nanoparticles of average particle size 5.0 to 12.0 nm were observed by transmission electron microscopy. FTIR spectra confirmed the presence of Ag−O bonding. Thermal studies were carrie...

Antimicrobial effects of green synthesized silver nanoparticles using Melissa officinalis grown under in vitro condition

Objective(s): To evaluate the biosynthesis of Ag NPs using plant extract of Melissa officinalis (at the eight leaf stage) grown under in vitro (controlled) condition for the first time.Materials and Methods: Biosynthesis of Ag NPs using plant extract was carried out and formation of Ag NPs confirmed by UV-Visible spectroscopy, X-ray diffraction (XRD), Field Emission Scanning Electron Microscope...

Obliteration of bacterial growth and biofilm through ROS generation by facilely synthesized green silver nanoparticles

Mangifera indica inflorescence aqueous extract was utilized for production of green AgNPs. Synthesized AgNPs were characterized by UV-vis spectrophotometry, XRD, TEM, FESEM and particles size analyzer. AgNPs showed minimum inhibitory concentrations (MICs) of 8 μg ml-1 and 16 μg ml-1 for Gram negative (K. pneumoniae, P. aeruginosa and E. coli) and Gram positive (S. mutans and S. aureus) strains,...

Antibacterial properties of silver nanoparticles synthesized using Pulicaria glutinosa plant extract as a green bioreductant

The antibacterial properties of nanoparticles (NPs) can be significantly enhanced by increasing the wettability or solubility of NPs in aqueous medium. In this study, we investigated the effects of the stabilizing agent on the solubility of silver NPs and its subsequent effect on their antimicrobial activities. Silver NPs were prepared using an aqueous solution of Pulicaria glutinosa plant extr...
