Chemicals typically available in plants have the capability to reduce silver and gold salts and to create silver and gold nanoparticles. We report the preparation of silver nanoparticles with sizes between 10 and 300 nm from silver nitrate using fruit extract collected from pineapples and oranges as reducing agents. The evolvement of a characteristic surface plasmon extinction spectrum in the r...

Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...

The aim of this study is to assess the acute toxicity of silver nitrate in adult zebra fish and adult guppies and to compare the sensitivity of these species to this compound. Silver is a naturally occurring element in our environment and it combines with other elements such as sulfide, chloride, and nitrate. Silver, in the form of silver nitrate, is one of the most toxic metals affecting fresh...

In this study, the parameters affecting the synthesis of silver nanoparticles were optimized by green chemical reduction method to make a conductive pattern. The raw materials used in this study, include silver nitrate as a source of silver ions, polyvinylpyrrolidone as surface stabilizer, and glucose as the reducing agent. Effective parameters were investigated by Taguchi statistical design,...

The first continuous silver polyhedra framework containing four kinds of coordination spheres has been successfully prepared by the reaction of silver(I) nitrate and 4(1H)-pyridone-3-sulfonic acid. This polyhedra framework is constructed from four kinds of silver(I) polyhedra by sharing corners, edges and faces.

silver salts and nanosilver (ns) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. therefore, in this study, the possible dermal toxicity of ns particles and silver nitrate (agno3), was tested by determining the serum level of transforming growth factor-β1(tgf-β1) and study on of mouse skin tissue. in this study, 30 balb...

Many modifications have been suggested for the determination of chloride in blood and other body fluids. The simplest and most thoroughly studied is a method proposed by Van Slyke (1) involving ashing of serum with concentrated nitric acid in the presence of silver nitrate to prevent volatilization of the chloride. In making a preliminary study of Van Slyke’s method before using it for a series...

Background and Objective: Nanoparticles have been introduced as novel antimicrobial agents because of their properties that are different from their bulk properties. Present study was aimed to investigate antimicrobial activity of silver nitrate and zinc oxide nanoparticles against three main bacteria responsible for nosocomial infections, S. aureus, P. aeruginosa and A. baumannii. Materials a...

N THE SEARCH for an accurate, rapid, versatile micromethod for chloride determination attention was focused on the simple but interesting dissimilar electrodes of Clark (1). Cunningham and coworkers (2) adapted these electrodes to measure 0-1 sMol of chloride with an error of less than 1 per cent. The chloride in a solution of sulfuric acid was titrated with standardized silver nitrate. The end...
