Today green synthesis of silver nanoparticles (SNPs) from plants is an utmost emerging filed in nanotechnology. In the present study, we have reported a green method for synthesis of SNPs from aqueous stem bark extract of Syzygium alternifolium, an endemic medicinal plant of South Eastern Ghats. These green-synthesised nanoparticles are characterised by colour change pattern, and the broad peak...

In this work, we have synthesized spherical silver nanoparticles (Ag NPs) by a low-cost, rapid, simple and ecofriendly approach using Date palm 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), tran...

A novel method to produce solution-phase triangular silver nanoparticles is presented. Ag nanoparticles are prepared by nanosphere lithography and are subsequently released into solution. The resulting nanoparticles are asymmetrically functionalized to produce either single isolated nanoparticles or dimer pairs. The structural and optical properties of Ag nanoparticles have been characterized. ...

The optimum conditions for the fabrication of zein/Ag composite nanoparticles from ethanol/H₂O cosolvents using electrospinning and the properties of the composite were investigated. The zein/Ag nanoparticles were characterized using field-emission scanning electron microscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis. The antibacterial act...

we have used lithium aluminum hydroxide reducing method of silver nitrate to prepare heterogeneous silver-silica nanocomposite particles with thiol and amino groups serving to bind the ag nanoparticles to the surfaces of the sio2 nanoparticles. we examined products of these reductions using ftir, sem, xrd and uv-vis. spectroscopy. the sio2 nanoparticles had diameters ranging from 70 to 90 nm; t...

Novel antimicrobial nanocomposite incorporating halloysite nanotubes (HNTs) and silver (Ag) into zinc oxide (ZnO) nanoparticles is prepared by integrating HNTs and decorating Ag nanoparticles. ZnO nanoparticles (ZnO NPs) and Ag nanoparticles (Ag NPs) with a size of about 100 and 8 nm, respectively, are dispersively anchored onto HNTs. The synergistic effects of ZnO NPs, Ag NPs, and HNTs led to ...

The novel approach has been carried for the green synthesis of silver nanoparticles using leaf extract of Cinnamomum tamala and silver nitrate solution. The optimal condition for synthesizing Ag-NPs was obtained by varying the leaf extract concentration, temperature, AgNO3 concentration, effect of ratio of leaf extract to AgNO3 solution,pH and reaction time. The f...

Silver (Ag) nanoparticle-loaded strontium titanate (SrTiO₃) nanoparticles were attempted to be synthesized by a sol-gel-hydrothermal method. We prepared the titanium oxide precursor gels incorporated with Ag⁺ and Sr2+ ions with various molar ratios, and they were successfully converted into the Ag-SrTiO₃ hybrid nanoparticles by the hydrothermal treatment at 230 °C in strontium hydroxide aqueous...

a simple, fast and one-pot synthesis procedure based on the bioreduction ability of an algal extract solution has been developed to produce silver nanoparticles (agnps). we focus especially on the influencing factors of agnps formation. the effects of various factors like ph, temperature, the concentration of metal ions and alga, the volume ratio of silver nitrate solution to alga extract, reac...
