conclusions the synergistic effect was found on the healing of infected wounds caused by s. aureus by using an mbp-1 and silver nanoparticles combination in a mouse model. results the mic and mbc of mbp-1 were found to be 0.6 and 0.7 mg/ml, respectively. mic and mbc of silver nanoparticles were determined to be 6.25 and 12.5 mg/l, respectively. mic and mbc of the silver nanoparticles and mbp-1 ...
in this paper we report an eco-friendly route for the synthesis of sliver nanoparticles using agaricus bisporus (white button mushroom) extract. the synthesized silver nanoparticles were confirmed and characterized by uv-visible spectrum of the aqueous solution containing silver ions showed a peak at 420 nm corresponding to the surface plasmon absorbance of silver nanoparticles. transmission el...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
Silver nanoparticles are widely used in various sciences and industries. Widespread use of silver nanoparticles has caused entrance of it to the aquatic environment through Wastewater, so it is necessary to investigate the effects of silver nanoparticles on various aquatic organisms. The present study investigated the lethal concentration and bioaccumulation of silver nanoparticles and its comp...

Objective(s): This study aimed to compare impacts of silver nanoparticles and silver cobalt nanoparticles on the hepatic function tests and changes in liver tissues in adult male rats.Materials and Methods: This study was conducted on 49 adult male Wistar rats, each weighing approximately 180-220 gr. The rats were randomly assigned to seven groups of seven including one control group and six ex...
a novel silver (ag) nanocomposite electrode was proposed that fabricated from metal nanostructures and ionic liquids. the combined application of unique properties of nanomaterials and ionic liquids in the design of this ag nanocomposite results in electrodes with interesting advantages compared to the conventional metal disk electrode. in the first part of this thesis, the elecrocatalytic eff...
Background and Objective: Today, silver nanoparticles are used extensively in various fields, especially in the control of bacterial infections. However, the toxicity of silver nanoparticles is a very important concern in their use. The aim of this study was determining the effect of the intraperitoneal injection of colloidal silver nanoparticles on biochemical and hematological parameters in r...
The study aims at synthesizing silver nanoparticles using leaf extract of Cymbopogon citratus along with the evaluation of its antioxidant, free radicals scavenging, and reducing power properties. Biosynthesized silver nanoparticles were characterized X-Ray diffractometry, Scanning Electron Microscopy, Transmission Electron Microscopy, Fourier Transform Infrared spectroscopy and Energy Dispersi...
In recent science Nanotechnology is a burning field for the researchers. To meet the requirements and growing technological demand, there is a need to develop an eco-friendly approach. In the present effort, the baker’s yeast (Saccharomyces cerevisiae) has been taken in order to assess its potential as putative candidate fungal genera for the transformation of silver nanoparticles. Silve...
