background acinetobacter baumannii plays a significant role in nosocomial infections. multidrug-resistant a. baumannii is recognized to be among the most difficult antimicrobial-resistant gram-negative bacilli to be controlled and treated. for this reason we examined the efficacy of nanosilver material with strong disinfectant properties against different types of bacteria. objectives the purpo...
nanotechnology has been advanced since the last decades. among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. its release into natural water bodies is inevitable due to its broad applications. nanosilver (nag) was prepared via tollens method using. the morphology, size distribution and average size of the obtained nag was characterized using tr...
Nanosilver: Safety, health and environmental effects and role in antimicrobial resistance Philippe Hartemann, Peter Hoet, Ana Proykova, Teresa Fernandes, Anders Baun, Wim De Jong, Juliane Filser, Arne Hensten, Carsten Kneuer, Jean-Yves Maillard, Hannu Norppa, Martin Scheringer, Susan Wijnhoven European Commission, Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) Corr...
Nanosilver was modified by aptamer (ssDNA) to obtain a resonance scattering (RS) probe (AgssDNA) for melamine (MA). Based on the catalytic effect of the probe on the Fehling particle reaction, a nanocatalytic RS assay is proposed for the determination of 0.02-1.06 μg L(-1) MA.
BACKGROUND Bacterial resistance against the classic antibiotics is posing an increasing challenge for the prevention and treatment of infections in health care environments. The introduction of antimicrobial nanocoatings with active ingredients provides alternative measures for active killing of microorganisms, through a preventive hygiene approach. PURPOSE The purpose of this study was to in...
Biosynthesis of nanosilver by using sweet orange (C. sinensis) as a bioreductor has shown nanosized results. In this research, the effect volume variation juice and peel extract combination toward characteristics antibacterial activity synthesized will be studied. Solution AgNO3 1 mM was mixed with – ratios (v/v), 3:0; 1.5:1.5; 1:2; 0.5:2.5 0:3 at 60˚C for 45 minutes. The color change solution ...
Silver ion has been used for centuries to prevent and treat a variety of diseases and infections. In recent years, extensive studies have been undertaken on the use of antimicrobial properties of silver, incorporated within medical devices. The aim of this study was to prepare a formulation containing silver ion, which could be applied for wound dressing. The purity of nanosilver was measured b...
this study was conducted to compare the effect of various commercial in-feed disinfectants on layer performance, intestinal microflora, and egg cholesterol. one hundred and eight layer hens (lsl, 24 wks of age) were divided into six groups consisting: control, formaycin-200 ppm, formalin-200 ppm, and nanosilver in feed-15 ppm or drinking water-7.5 ppm. there were no differences between experime...
Nanosilver (10−9 m) refers to particles comprising 20–15,000 silver atoms, exhibiting high stability and specific surface area. At present, nanosilver has been used in agricultural cultivation production. This study examined the effects of on growth development rice root systems. Study results showed that fresh weight belowground organs length both increased significantly by 5% 25%, respectivel...
