This paper presents the improvement of the antimicrobial character of woven fabrics based on cotton. The woven fabrics were cleaned in oxygen plasma and treated by padding with silver chloride and titanium dioxide particles. The existence of silver and titanium on woven fabrics was evidenced by electronic microscope images (SEM, EDAX) and by flame atomic absorption spectrophotometry. The antimi...

Tumor growth is characterized by uncontrolled cell division. For centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional Iranian and Pakistani medicine for the treatment of melanoma and breast cancer. We have found that these nanocomposite particles are similar to silver nanoparticles (AgNps) in size and shape and that there are so differenc...

It was reported that during silicon etching, silver was subjected to have a controversial role. Some researchers debate that silver protects silicon, and, at the same time, other ones confirm that silver catalyzes silicon underneath. In this paper, we give experimental results arguing the dual role that silver has during the formation of silicon nanostructures. We give a proof that the role of ...

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, ...

Antibiotic resistant pathogens pose an enormous threat to the treatment of various serious infections. To overcome this condition, a periodic replacement of the new and existing antibiotic is necessary. Antibiotics in combination with biosynthesized silver nanoparticles minimize the antibiotic doses to cure the dreaded diseases. In this study, Silver nanoparticles were bio-synthesized by extrac...

The authors present results of studies on commercially available silver nanoparticles fabricated by Amepox Microelectronics and delivered in the form of silver powder. The studies were carried out by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and scanning tunnelling microscopy (STM). Chemical analysis performed with the use of EDX revealed that the powder contain...

Due to the widespread use of silver nanoparticles in consumer products, the toxicity of silver nanoparticles has also been studied in relation to their application. However, most genotoxicity studies of silver nanoparticles have been performed in vitro. Therefore, this study evaluated the DNA damage to lung cells caused by repeated inhalation of silver nanoparticles. Male Sprague Dawley rats we...

Silver metal was recovered primarily from spent X-ray photographic solution using a horizontal tube furnace. The X-Ray Diffraction (XRD) spectroscopy analysis approved almost 95 percent purity of the recovered silver metal. In the next step, the synthesis of silver nanoparticles from the recovered silver metal proceeded by using chemical reduction method. The proposed method uses e...

Uniform silver nanoparticles have been prepared through the chemical reduction of silver ions by ethanol in presence of sodium linoleate. TEM micrograph shows a uniform distribution of the particles with an average size of 12 nm. Further, the antimicrobial activity of silver nanoparticles shows that these nanoparticles can be used as effective growth inhibitors against Staphylococcus Basillus, ...
