BACKGROUND AND THE PURPOSE OF THE STUDY The most prominent nanoparticles for medical uses are nanosilver particles which are famous for their high anti-microbial activity. Silver ion has been known as a metal ion that exhibit anti-mold, anti-microbial and anti-algal properties for a long time. In particular, it is widely used as silver nitrate aqueous solution which has disinfecting and sterili...

In this paper, results on preparation of stable and uniform SERS solid substrates using macroporous silicon (pSi) with deposited silver and gold are presented. Macroporous silicon is produced by anodisation of p-type silicon in hydrofluoric acid. The as prepared pSi is then used as a template for Ag and Au depositions. The noble metals were deposited in three different ways: by immersion in sil...

Silver nitrate and aminoethoxyvinylglycine (AVG) are often used to inhibit perception and biosynthesis, respectively, of the phytohormone ethylene. In the course of exploring the genetic basis of the extensive interactions between ethylene and auxin, we compared the effects of silver nitrate (AgNO(3)) and AVG on auxin responsiveness. We found that although AgNO(3) dramatically decreased root in...

Recently there has been fabulous excitement in the nano-biotechnological area for the study of nanoparticles synthesis using some natural biological system, which has led the growth advanced nanomaterials. This intention made us to assess the biologically synthesized silver nanoparticles from the leaf of Suaeda monoica (S.monoica) using 1 mM silver nitrate. The leaf extract of S.monoica incubat...

Systematic studies of silver nanoparticle synthesis in a continuous-flow single-mode microwave reactor using polyol process were performed, revealing that the synthesis is exceptionally effective to give very small metal particles at full reaction yield and very high productivity. Inlet concentration of silver nitrate or silver acetate, applied as metal precursors, varied between 10 and 50 mM, ...

Biosynthesised nanoparticles have wider applications in medical and pharmaceutical fields. In our study aims to synthesis silver nanoparticles using biological source Serratia marcescens. The nano particle synthesis was optimized with different pH of the culture medium and concentration of metal salts that affected the nanoparticles formation during synthesis. Culture medium with different pH s...

Silver particles less than 20 nm in diameter were synthesized by pyrolysis of an ultrasonically atomized spray of highly dilute aqueous silver nitrate solution at temperatures above 650◦C and below the melting point of silver. Feed solution concentration and ultrasound power applied to the atomizer were found to have a significant impact on the particle size of the silver nanoparticles. Average...

Silver nanoparticles were obtained via totally green synthesis from silver nitrate using glucose as reducing agent and sucralose as capping agent. Physico-chemical characterization of AgNPs was performed by UV-Visible absorption and transmission electron microscopy (TEM) in order to correlate biological/toxicological responses with AgNPs features. A detailed study of silver nanoparticles (AgNPs...

background : pseudomonas aeruginosa , as an etiological agent, has a prominent infection role in serious burned patients. burned patients usually treated with antiseptic ointments such as silver sulfadiazine (ssd). this study evaluated the effectiveness of 1% ssd and different concentrations of silver nitrate solution (sns) on resistant isolates of p. aeruginosa .   methods : three groups of p....

Stable silver nanoparticles were successfully synthesized by chemical reduction of silver nitrate in ionic liquids 1Ethyl-3-methylimidazolium tetrafluoroborate [Emim] BF4 and 1Ethyl-3-methylimidazolium hexafluorophosphate [Emim] PF6 at room temperature. The characterization of the silver nanoparticles such as their size and shape was performed by X-ray Diffraction (XRD) and Scanning Electron Mi...
