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 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 ...
