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...

The resonance behavior of localized surface plasmons in silver and gold nanoparticles was studied in the visible and near-infrared regions of the electromagnetic spectrum. Arrays of nano-sized gold (Au) and silver (Ag) particles with different properties were produced with electron-beam lithography technique over glass substrates. The effect of the particle size, shape variations, period, thick...

Applying our photo technology, we succeeded in generating silver particles exceeding 10 μm by using 50 nm gold particles as catalysts, which are commonly used in commercially available influenza diagnostic kits. The amplified silver particles are 1,000 times easier to see than gold nano-particles. We have commercialized the influenza detection kit, named “FUJI DRI-CHEM IMMUNO AG cartridge FluAB...

BACKGROUND Nanobiotechnology applies the capabilities of biological systems in generating a variety of nano-sized structures. Plants, algae, fungi and bacteria are some systems mediating such reactions. In fungi, the synthesis of melanin is an important strategy for cell-survival under metal-stressed conditions. Yarrowia lipolytica, the biotechnologically significant yeast also produces melanin...

Silver coordination polymer chains were deposited on Au(111) as a model surface, as well as on gold alloy and titanium as dental implant and restorative materials. The topography of the surface was analysed on the model substrate and it was found to be a nano-structured crystalline material. In vitro investigations in a flow chamber imitating the oral environment prove the anti-bacterial proper...

This work presents simulation, analysis and implementation of morphology tuning of gold nano-island structures deposited by a novel convective assembly technique. The gold nano-islands were simulated using 3D Finite-Difference Time-Domain (FDTD) techniques to investigate the effect of morphological changes and adsorption of protein layers on the localized surface plasmon resonance (LSPR) proper...

according to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. the low value residual gold ions existed in acid leaching tail solution in mouteh gold mine in iran with fellow heavy metals as pollutants (fe2+, cu2+, and zn2+). preparation of nano gold particles is achieved by two steps: first, by addition of ammonia as separatio...

The aim of this study is experimental assay of sensitivity and stability of a bimetallic silver/gold SPR sensor chip. This chip utilizes the sensitivity of the silver and the stability of the gold. Moreover, the Silver layer (instead of usual Cr or Ti layer) was used as an adhesive intermediate layer between the Gold layer and the glass substrate. The optimization of the Gold/Silver thickness u...

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

Biofilm formation on implant materials causes a common problem: resistance to aggressive pharmacological agents as well as host defenses. Therefore, to reduce bacterial adhesion to implant surfaces we propose to use silver(I) coordination networks as it is known that silver is the most powerful antimicrobial inorganic agent. As a model surface, self-assembled monolayers (SAMs) on gold Au(111) w...
