the aim of this study was to assess the meat quality attributes of broiler chickens fed diets supplemented with silver nanoparticles coated on zeolite. a total of 375 one-day-old broilers was assigned in a completely randomized design to 1 of 5 treatment groups including: basal diet, basal diet supplemented with 1% zeolite, and basal diet supplemented with one of the three levels of zeolite coa...

objective: nanosilver has numerous applications in medicine due to its potent antibacterial activity. however, data regarding the bio-safety of its effective concentrations is scarce. this study aims to assess the toxicity of silver nanoparticles on human gingival epithelial cells under in-vitro conditions.   methods: this in vitro study evaluated the toxic effects of filtered and unfiltered na...

objective(s): nanosilver is one of the most widely used nanomaterials due to its strong antimicrobial activity. thus, because of increasing potential for exposure of human to nanosilver, there is an increasing concern about possible side effects of these nanoparticles. in this study, we tested the potential dermal toxicity of nanosilver bandage on serum chemical biomarkers in mice.  materials a...

Silver has long been known to have antimicrobial properties and were used until chemical antibiotics came into vogue. Metallic silver and most inorganic silver compounds ionize in moisture, body fluids and secretions to release biologically active Ag+, which the silver ions have been used for the characteristics of toxicology and pharmacology as antimicrobial agent.1 Nanosilver particles have b...

Nanosilver has recently been recognized as an antimicrobial agent. Although this nanoparticlecan be used in medical applications but its dermal and systemic toxicity via dermal exposure hasnot been completely determined yet. The aim in this study was to investigate the potential dermaltoxicity of Nanosilver in subchronic method. Before the colloidal silver nanoparticle toxicityevaluation, their...

Nanotechnology is a new and specific method for therapy of diseases. Nanosilver particle is one of the functional fields of nanotechnology. It has been shown that these nanoparticles have antibacterial and antifungal properties. Different studied have been shown that nanoparticles may have important role in medicine. For example, it has been shown to have inhibitory effects on the treatment of ...

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...
