Silver nanocomposite coatings are prepared by the sol-gel method for the prevention of biofilm formation on the surface of medical implanted devices. High-temperature processing of such coatings can lead to diffusion of nanosilver and reduce the amount of available silver particles for long-term effects. Using a low-temperature sol-gel method, we have successfully prepared silane-based matrices...

The widespread use of silver nanoparticles (AgN) in the articles of common use justifies the need to investigate their effects on the human body. Nanosilver toxicity of highly purified, stable, and well-characterized Ag sol toward human immune cells at various differentiation stages has been studied. Human promyelocytic leukemia cells (HL-60) were differentiated to granulocytes using dimethyl s...

effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with borax. nanosilver and borax were applied in pressure vessel using rueping method. the size range of silver nanoparticles was 20-80 nm. specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...

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.
