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...

As an important interconnection material in electronics, conductive silver paste has attracted much research interest chip packaging and printed circuit board due to its predominant properties like high conductivity flexible interconnection. In this paper, the nanoparticles, sphere particles, flake powders are fabricated by various methods. Different proportions of powder selected prepare micro...

The present study was aimed at evaluating the fluorescence property, sporicidal potency against Bacillus and Clostridium endospores, and surface disinfecting ability of biogenic nano silver. The nano silver was synthesized using an actinobacterial cell-filtrate. The fluorescence property as well as imaging facilitator potency of this nano silver was verified adopting spectrofluorometer along wi...

Nano packaging is currently one of the most important topics in food packaging technologies. The aim of the application of this technology in food packaging is increasing shelf life of foods by preventing internal and external corruption and microbial contaminations. Use of silver nanoparticles in food packaging has recently attracted much attention. The aim of this study was to investigate the...

in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...

Silver nano-particles have been used for antibacterial purpose and it is also believed to have removal of odorous compounds, oxidation capacity as a metal catalyst. In this study, silver nano-particles in nano sizes (5-30 nm) were prepared on the surface of NaHCO3, the supporting material, using a sputtering method that provided high silver content and minimized conglomerating problems observed...

OBJECTIVES Silver has long been known as a strong antimicrobial and disinfectant. Several types of nano-silver coated products have been developed. However, the antimicrobial and disinfectant characteristics of nano-silver have not been well studied. The aim of this study was to investigate the effect of nano-silver on allergic inflammation in a mouse model. METHODS Female BALB/C mice were se...

BACKGROUND The aim of this study was to evaluate the effect of nano silver and silver nitrate on yield of seed in basil plant. The study was carried out in a randomized block design with three replications. RESULTS Four levels of either silver nitrate (0, 100, 200 and 300 ppm) or nano silver (0, 20, 40, and 60 ppm) were sprayed on basil plant at seed growth stage. The results showed that ther...

A nano-composite powder composed of silica and carbon with a unique property could be prepared from a mixture of a silicate compound and an epoxy compound, in which the silica within the nano-composite powder has a BET surface area of as high as greater than 800m2/g although the nano-composite powder has a BET surface area of less than 10m2/g. It was estimated that the silica and the carbon are...
